On average, the typical A5 sized notebook (Leuchtturm, Hobonichi, Stalogy, Moleskine, Midori, Clairefontaine, Apica, Kleid, etc. ranging from 192 to 368 pages) has an equivalent square footage of writing surface to the front (only) of about 420 4 x 6 inch index cards. On a cost basis, for the same amount of money, on average one can buy 1,200 index cards for what they’re shelling out for equivalent notebooks.
I’ve had an oddly large number of emails over the past few months asking me for advice about what sorts of index card cases and carrying options I use on a daily basis. Rather than tip out my zettelkasten in fits and spurts on the topic, I thought I’d pour out all those ideas out here instead.
If you’re all-in on the ever-growing neo-index card lifestyle, then you should really work at adding some actual style to your fichier boîte practice. If your note taking has you going through cards like water, you’ll likely want something to carry them on the go, and often it can be useful, especially in meetings, to have something that not only looks nice, but will hold up through heavy use over the years. Maybe you want something fashionable to fit the change of seasons? Something to suit the occasion whether it’s a corporate board meeting or something to go with your red carpet black tie look? Are you taking notes at romantic wedding get-aways or at the beach? What are you using for storage?
In the vein of my article The Ultimate Guide to Zettelkasten Index Card Storage, below I’ve collected a number of various sorts of daily carry index card cases, wallets, covers, and folios one might consider using. Some, where indicated, are items I use regularly, but others are interesting options I’ve run across in my travels, and though they didn’t fit my particular needs, they might fit yours. I don’t (yet) consider it to be the ultimate guide to this space, so if you’re in the market, feel free to check back occasionally or add your thoughts, suggestions, or reviews to the comments below. Since some items aren’t designed specifically for index cards, notes about their usability and portability with respect to note taking or zettelkasten practices are appreciated.
As I did for boxes, I’m going to focus primarily on the 3 x 5 inch and 4 x 6 inch index card form factors which are more common, and for which these products are often more readily available. If you’re using larger cards, then you might consider searching for folders, cases, and related containers for equivalent sizes of paper in terms of notebook covers, filing solutions, and other binders keeping in mind that equivalent European or DIN A-sizes (A5, A4, etc.) may also suit your needs as long as they’re big enough to physically accommodate your cards. If you find something spectacular, let us all know.
Please double check sizing as I have run into instances where some items were fractions of an inch too small to fit the cards I wanted to use.
If you’re doing your own targeted searches some of the following words can be useful: cases, wallets, covers, pocket briefcases, folios, pouches, bags, pen and/or pencil cases, and fountain pen cases. While some of the pen related cases may not be as suitable, some are free-form pouches which will easily accommodate index cards in addition to other items you may want to carry with your cards. You can’t take notes without a writing instrument, so having space for a pen or pencil or two isn’t a bad thing. You’ll probably notice that some items come with pen loops for such eventualities. Trawling through some of the fountain pen and stationery communities can also give you some creative ideas for portable index card storage.
While not the most spectacular option, this double zippered, expandable pen case fits a huge number of pens and small office supplies as well as loads of either 3 x 5 or 4 x 6 inch index cards.
It bears noticing that one could also go the DIY route and make their own portable index card holders. This would allow one to have the exact form factor and specifications for their personal note taking styles. If this is you, hopefully some of the options below will give you some ideas about what form factors are available for designing your own. You’ll find that there are options in a variety of materials including leather, cotton, canvas, waxed canvas, sailcloth, metal, and even Harris Tweed.
What will you choose?
Size independent options
Before we delve into some of the card size-specific choices, let’s look at a few that are size independent.
Binder Clips. Everyone is likely aware of it, but we will mention that in true old-school hipster PDA-style (aka Parietal Disgorgement Aid), one could certainly use a binder clip, which makes a certain statement, though not the one that many might wish. In a similar vein, I’ve heard people say they rely on rubber bands, or especially in hot climates where rubber bands break down quickly, plastic sandwich bags (Ziploc to keep out the moisture), or even envelopes. Envelopes may present an intriguing practice for those into slip-based project management or forms of kakeibo (家計 簿).
The classic Hipster PDA dressed up with a brass binder clip.
Binder rings. If you want to go flashcard style, then you’ll want to search for a good hole punch (I recommend the Mutual Centamatic Punch No. 250) and some binder rings which come in a huge variety of sizes, materials, and even colors.
Chicago Binding Screws. If you appreciate the flashcard style, but not the esthetic and would rather look a bit more corporate than playground, then perhaps Chicago binding screws (available in various sizes and finishes) will give your deck of index cards a more buttoned up look? For those who are fans of index card filing rod solutions, these can also be used to bundle up cards on the go using your pre-punched cards. Higher end metal finishes (brass, copper, oiled bronze?) can really up the game on this option.
Gangnam Style. Just kidding—I’m just checking to see if you’re still awake. But seriously, the stiff upper body movements in the video were the result of decks of index cards in the suit jackets. I swear!
Uninspired Plastic. If you really must… Only for the indiscriminate completists, I’ll mention the ubiquitous cheap plastic cases, some with snaps or elastics for closure which hold 50 to a few hundred cards. If you carefully follow some of the zettelkasten box market, you can get a solid antique or vintage wooden box for almost as much as you’d pay for a dozen of these cheap toys. I don’t want to shame anyone, particularly those who are still test driving the analog index card life, but perhaps this is what you’ve got now and you’re here searching for a modest upgrade? Good! Keep exploring to find your new index card lifestyle.
Everyone has a few of these plastic holders lying around. Do they spark joy? Probably not.
3 x 5 inch index card versions
Not only are there a variety of custom solutions specifically designed for 3 x 5 inch index cards, but one can also profitably search for and use items designed for passports (3.5 x 5 inches) or pocket notebooks which are slightly larger, but still serviceable. A variety of high quality solutions are designed specifically for a variety of common brand name pocket notebook products including Field Notes (3.5 x 5.5 inches), Moleskine (3.5 x 5.5 inches), Leuchtturm (A6), Hobonichi, Midori, Jibun, etc., so searching for these within the space can provide some additional options for the discerning buyer.
In some cases, products meant for A7 size paper (74 mm x 105 mm or 2.91 x 4.13 inch) may also work, but check the sizing as A7 is physically smaller than 3 x 5 inches. Similarly A6 size paper (105 x 148mm or 4.13 x 5.83 inches) products should work as they are slightly larger than both 3 x 5 inch and 4 x 6 inch index cards, though depending on your card size they may be a bit roomy.
Products
Simple leather wallets. I have an inexpensive, but nice leather notebook cover/wallet that I usually have a few 3x5s in. Searching for covers for pocket notebooks or A6 notebooks one will find lots of these which are more ubiquitous than those that will hold the larger 4×6 inch cards. Hundreds of variations of this sort can be found on Amazon, Etsy, eBay, and other online and leather retailers. After you’ve seen a few you can pick and choose ones with the number of pockets or slots you’d like, whether or not you want a pen loop, the ability to use it as a wallet for your cash and credit cards along with your notes, etc. Prices can generally range from US$15 to well over $100 with a variety of colors, types of leather, and even personalization options.
Passport wallets. Similar to the above, there are a huge number of commercially available passport wallets in a variety of shapes, configurations, and materials. Most should fit index cards within the pocket designed for the passport. Search and see what you come up with. One correspondent said they loved their Aspinal of London passport cover.
Levenger carries some nicer index card-specific “pocket briefcases”. Their offerings are only for 3 x 5 inch form factors, but they do have a variety of those size cards and small notebooks as well as the ability to custom print stationery at that size if you’re looking for something personalized.
Kaitiaki has a unique form factor. It not only holds cards, but can be stood up as a display as well as be used as a small writing desk while you’re on the go.
Rite in the Rain has a variety of notebooks and index card products whose primary premise is that they are waterproof. Naturally they also carry a variety of protective cases and pouches, most made of cordura, with a variety of configurations to suit a variety of needs. Browsing around here will find a variety of interesting and rugged options. Also of note, they have an index card wallet designed specifically for 3 x 5 inch index cards. Some may also appreciate their field desks for writing on the go. Slightly more difficult to find amid their cordura offerings are their Guide and Sherpa leather wallets which should comfortably fit 3 x 5 inch cards.
Lochby is primarily in the notebook and planner space with a variety of offerings featuring a durable waxed canvas esthetic. Their Pocket Journal case, meant for pocket notebooks, will easily hold a hundred index cards with additional internal pockets for business cards or credit cards and external pockets for miscellanea as well as a pen. It is small enough one could use it as a wallet and it will fit in most back pockets, though depending on its contents, it may not be comfortable to sit on for extended periods. Their larger Venture Pouch has two zippered sides, one for pens and the other with two separate spaces for index cards or other portable office supplies. If you don’t mind a bit more bulk in your portable office, Lockby’s Tool Roll should easily fit 150 index cards along with a variety of pens and side pocket for miscellaneous needs. If you’re price sensitive, sign up to their newsletter as they have regular sales and discounts throughout the year.
IF provides some off-the-beaten-path options for the avid reader and note taker. Of particular note in their line up, is the Bookaroo Notebook Tidy, which is available in a number of colors. It provides eight elastic bands on the front for a variety of storage options, one of which could easily be your 3 x 5 inch index cards (it sadly won’t fit 4 x 6 inch though one could use a binderclip to attach them to the back of the tidy in a pinch). Turned over, the back is a firm surface that could be used as a small writing desk. Also included is an adjustable elastic band which can be used to attach the tidy to an A5 notebook or to a wide variety of standard hardcover novels and non-fiction (9.5 inch tall) books. Just attach your tidy with some note cards and you’re ready to read and take notes at your favorite home away from home.
Rickshaw, an offshoot company from Timbuk2 bags, offers a wide array of bags, wallets, pouches, and miscellanea in a huge variety of materials and form factors. While some of their larger items will certainly fit 3 x 5 inch cards, some of their smaller offerings include: The Diplomat, a wide variety of pocket notebook folios, and lots of pouches and wallets.
Traveler’s Notebook manufactures passport size notebook covers meant for their range of notebooks which are held in by way of elastic bands. This makes them potentially less useful the index card afficionados as unbound or unclipped cards may not stay in them as easily. However, if you’re making or using small index card pads of the sort I’ve discussed in the past, then you can easily slip them in and go. TN also makes a variety of other useful inserts which may make this a intriguing choice.
4 x 6 inch index card versions
In this category, there aren’t as many custom made solutions, so searching specifically for them has generally been fruitless. The better bet for this size factor is to search for the slightly larger A6 sized notebook covers, holders, cases, and pouches and be comfortable with them being slightly larger. In most of my experience this is fine and there’s isn’t so much extra space that the difference is worrisome or noticeable. Some particular brands that might work include Hobonichi, The Superior Labor, Leuchtturm, etc.
Products
King Jim makes the cotton Flatty Works #5460, an A6 horizontal pouch with small internal and external thin pockets and a clear front plastic window. At H4.8×W6.8×D1.4 inches it easily fits not only 4 x 6 inch index cards but has enough clearance for tabbed dividers as well. I have one I use as a daily carry and love it. I’ve written more details and a review elsewhere on the site.
Lochby. Mentioned above, their only product which will fit 4 x 6 inch cards is their “Adventure Pouch”. It will also provide you with space for a variety of pens, pencils, a pair of glasses and other small niceties. 4 x 6 inch cards won’t fit into the pockets of their tool roll (pictured above), but if it’s compelling enough, you could roll them into the apparatus and they shouldn’t fall out when clasped shut.
Rite in the Rain. Also mentioned in the 3 x 5 inch section, Rite in the Rain offers a handful of covers and pouches which are slightly bigger than 4 x 6 inch and will easily accommodate these index cards. Weatherproof, most are made out of cordura and have a rugged appearance and feel.
ateliers PENELOPE makes a variety of canvas bags and storage solutions, but their large Diary Pouch may be a classy solution for some of your larger index card on-the-go storage. Given its size, it’s got space for both index cards as well as some of your other portable storage needs. It’s small enough that it should fit easily into a briefcase or other larger bags or purses. If you have some index card “notebooks”, you might also consider their A6 canvas covers which are lovely and colorful.
Rickshaw. With a pedigree stemming out of Timbuk2, this San Francisco purveyor of bags for a variety of purposes offers two that look like solid options for the portable 4 x 6 inch index card fan (and which are certainly big enough for 3 x 5 inch users). The first is their Travelers Notebook Case and the second is the Coozy Case. Some may find that their larger A5 cases or their pouches may also suit their needs. The benefit of these options is that they come in a huge array of colors with customizable options. Browse around their site to see if something here strikes your fancy. Houndstooth anyone? Harris Tweed!?! Add-a-Patch? Yes, please. May I have some more?
Galen Leather. Galen, generally beloved within the fountain pen and stationery communities, offers a wide variety of leather notebook covers, folios, bags, and zippered cases which are compatible with a variety of index card sizes. One unique option here is their Writing Box, inspired by a writing desk owned by Thomas Jefferson.
Custom solutions
I’ve been trying to get Aaron Aiken to make a custom leather billfold/cover, but it’ll be a few months before he gets around to it. If this is of interest to you, do ping him with your interest. (See conversation thread for details.)
Thoughts?
Have I missed anything interesting?
What is your favorite index card holder when you’re out on the go? What’s holding your fleeting notes?
I’ve heard many people mention their issues with writing in new notebooks or coming up with ideas for what to put in their ever-growing collections of multiple brand new notebooks. Some feel like they’re just notebook collectors who appreciate the look and feel of a new notebook, pregnant with so much possibility. Others are frozen by the need for perfection and can’t bring themselves to write on a page. One writer told me that he purposely mars the first page in every new notebook, just to force himself to get over the fear of the newness and perfection—something he picked up from his dad who dinged with a hammer on day one every new car he bought to get over the preciousness of the new.
This is why I like having stacks of index cards at hand. They’re beautiful and lovely, but if you screw up or make a mistake, it’s just one card. Copy it and throw the imperfect one out if you need to. (Though I find in practice I don’t ever do this.) Because they’re not bound together, you’re also not bound by what you write on one card needing to fit in with what you write on any of the others. There’s no worrying about what subject you’re going to write on this one card tying you to something the way writing in a single subject notebook might. Did this sort of fear exist in the users of 17th century commonplace notebooks, or was it something that evolved in the 20th century with the idea of single subject school notebooks?
My nicest index cards don’t carry the same baggage as my nicest notebooks.
Over the weekend I had the good fortune to hear about a little stationery shop 10 minutes from my house. Baum-kuchen is a spectacular little space hiding over on Lincoln in Altadena with a warm, wabi-sabi (わびさび) charm. The business began in 2010, but opened up their physical location in 2019. Obviously not the most fortuitous time to have opened a brick and mortar location, they’re primarily still online, but have regular open hours usually from 12-5pm on Sundays.
The space, while modest, is rich and well-appointed, as one would expect a fine stationery store to be. I spent almost as much time appreciating the small touches of hardware for merchandising purposes as I did lusting after the stationery, pens, pencils, cases, bags, washi tape, stamps, paper twine, and miscellanea. I think the first three things I asked for prices on were store fixtures. (But with a lush, rare Wabash Cabinet on display, who wouldn’t?)
If you’re looking for the corporate, completist, and cramped feel of something like Kinokuniya, this is assuredly not that. This is a place to luxuriate in stationery and spark some creativity away from the madding crowd.
Of particular note, they’ve got one of the most beautiful, well-appointed, and fully stocked pigeonhole displays I’ve ever seen for Traveler’s Notebooks. They also offer a nice selection of The Superior Labor products to which they also offer customization touches you can easily add on to make your notebook “Truly Yours”.
They seem to have a full selection of MIDORI paper products, lots of Stalogy, and PERPANEP. Also on offer were analog planners like Jibun Techos, Roterfaden, and Nolty along with brands like Classiky, Kokuyo, Kuretake, Mizushima, Postalco, and ateliers PENELOPE among others.
I’ll take a moment to note that this was the first time I’ve ever seen Roterfaden for sale in a physical shop. They truly are lovely analog items with a high level of tactile joy. I find myself needing more thick felt in my life beyond the large grey mat I use for shodo.
This also reminds me that the shop does a fantastic job of providing physical samples of nearly almost every product that you can open, play with, and try out (including samples of most of the notebook paper!) It’s small touches like this that will keep the stationery afficionados coming back every time.
Community
In addition to all the spectacular things I saw, I would be remiss not to mention one of the kindest touches in the whole shop. Front and center in the main room is a fantastic wooden and metal table with several fine chairs. They invite the community to come in with their journals to sit and write with each other.
I arrived on the early side of their store hours, but just after, two people showed up who browsed for a bit, but then sat down to write and try out some of the available stamps on the table in their own journals. Wakako even invited me to feel free to bring my typewriter to sit and write for a bit in the future. Anyone up to join me? With such a nice space, why not use it on a Sunday afternoon to plan out your week or reflect on the week past?
Beyond the warm and inviting space, they keep things in stock in the store which seem to be marked as sold out in their online storefront. On first blush this could be written down as a potential accounting error or maybe delays in updating the website, but I suspect that they’re carefully holding onto stock for their local community to be able to see items and purchase things in person.
As rare as it is to see a shop revel in the idea of analog, it’s even more refreshing and heartening to see one doing its best to strive towards kindness within its own community the way that Baum-kuchen does.
Next time, with money in my pocket
I usually make a habit of leaving my wallet at home on first visits to nearby stationery stores. (Those inflicted with the gentle madness like me will know why.) But I’ve started a list on my pocket notebook with a few things I must have on my next visit…
There are too many things to like about Baum-kuchen, and I haven’t even mentioned the pastry origins of the German-named shop. Some will scream that I’ve buried the lede in this whole story when I mention the following exciting revelation: This fall, Baum-kuchen will be carrying a wide variety of Hobonichi products!!! I’m only aware of a tiny handful of US-based stores which carry or ship Hobonichi (JetPens anyone?), but Baum-kuchen will be one of them. I’ve generally ordered these directly from Japan in the past, but it will be ever so nice to be able to place an order to a physical shop that’s just a few minutes away. I’m hoping they’ll open up the store on announcement day and have a little party to celebrate. If they do, I’m definitely baking them a homemade tree cake!
Back on April 7th on a visit to the Kinokuniya bookstore/Maido stationery shop in the Santa Anita Mall, I picked up an A6 size horizontal Flatty Works case #5460 (forest green, H4.8×W6.8×D1.4in) made by King Jim. It was listed at US$20.50+tax. The case is also available in mustard yellow, beige, teal, and a dark blue.
It’s a nice little minimalist case made with a very lightly parafin-waxed cotton canvas material and a clear plastic front so that one can see the internal contents. The sides of the flexible case fold in accordion-style when not full so it collapses to fit the space it needs. In addition to the primary internal space, the case has a thin internal pocket that would accommodate some credit cards, a handful of 4 x 6 index cards, or perhaps a Field Notes pocket notebook. Similarly on the outside back, there’s an angularly cut external pocket for a few slips of paper, or to place the cover of your A6 notebook while writing. The front has an envelope-style closure flap with a reasonably strong magnetic snap.
I purchased the case primarily to carry my 4 x 6 inch index card “notebooks” as well as a variety of loose index cards and dividers I carry regularly. It has the benefit of going reasonably well with my collection of Lochby waxed canvas holders and covers as well. I usually keep a copy of today’s schedule and priority to do list on top of the interior pocket so they’re easily visible during the day through the clear plastic front of the case.
For the curious, I’ve tried them variously and can verify that the case also comfortably fits the following (separately):
A Samsung S22 cell phone and a few Field Note notebooks
An Amazon Kindle Paperwhite and a pack of 100 4 x 6 index cards
A reasonably thick A6 sized notebook along with some additional pens or simple office supplies. A small Hobonichi would easily fit with space to spare.
The case is small enough to comfortably fit into the back pocket of my blue jeans, for walking around, but it’s not super comfortable for sitting on that way, particularly for long periods. I like its portability and the ability to take out a few cards and work on them using the reverse side as a mini-desk while moving around throughout the day. In some sense it acts like a custom made folder for filing my index cards on the go as a everyday carry. It made for a reasonably comfortable mini-office while on an airplane last week.
The inside top left corner of the case has a small loop that would allow one to attach a string, key chain, carrying handle or other loop to attach the case to a purse or other bag if necessary. This might also be convenient for those who might want to use this case as a bag in a bag, though I’ve not personally had the need for it yet.
Even with only a few index cards inside, the case is easily capable of standing upright in front of my card index/zettelkasten on my desk to take up less space than lying flat. Doing this also keeps all my immediate cards easily accessible while also being ready to travel if necessary.
Thus far, after a few weeks of use and even some airplane travel, it’s shown itself to be sturdy, convenient, useful, and a lovely addition to my daily zettelkasten workflow.
Before I go the DIY route, has anyone seen gummed 4 x 6″ index cards available for sale? I’d love to have a bunch of index cards temporarily glued together almost in notebook form for easy use and portability.
I know there are a handful of manufacturers who make spiral bound versions with perforations for tearing cards out, but I’m looking for something a tad less bulky for putting in a back pocket or jacket pocket. I’ve also considered using binder clips and even book rings, but again, I’m trying to slim the system down.
If there’s nothing great, I may just go with my favorite cards and DIY with some PVA Glue which is often used in book binding and is suggested frequently in crafting videos like: https://www.youtube.com/watch?v=b-Wp0sLpnMY. In the end, this may be the best route to allow me to choose my favorite cards in addition to how thick I can make the “notebooks”.
Note card cases, folios, and holders
Similar/related/useful things I’ve come across in this related space:
YOAVIP 4×6 Index Cards Clear Plastic Holder looked interesting, but was a larger, notebook sized version, though still had some useful portability features, yet might be a bit persnickety for regular in-and-out usage.
Other ideas?
Has anyone else done this or anything similar? How about wallets, folios, or thin covers? What’s your experience?
