That's a huge collection! A lot of very nice products you listed there.

I find e.g. the Kaitiaki wallet to be a curious invention. An index card holder and wallet, sure, but turning it into a stand, like a tablet case, that's weird! -- I never used index cards in a way to make sense of propping up the card display like this, but someone seems to find use in this, and that took me by surprise :)

(I'm recycling some of the product tips for my list of Urban Sketching/painting equipment holding. Things that attach to sketchbook covers and that can hold a palette and water brushes are cute.)
