Yep, I've got a bunch left over from when I was a job printer. I made stationery for myself with 2-part & 3-part NCR, Results are unimpressive, as NCR isn't especially good at copies unless you're writing with a pen, hard, or using a dot-matrix printer. Typewriting tends to be very light on the copies, often unreadable, and you get feed roller stripes down the page. I gave up on it after a few months and switched to scanning my outgoing pages.
