Ok, guys, I've read it many times that coin envelopes (the paper kind) are practical for storing SMT. Much less space than all those cans the size of aspirin packages that stuff the cabinets here. Ok, not as airtight but that should be fine.

I asked at all kinds of stores, Tarjay, Walmart, Longs, stationary shops, you name it. None had any, most didn't even know what I was talking about. Where do you buy them?

Staples?

Well, not quite. The smallest they have is 2-1/4" by 3-1/2", quite large, doesn't fit into parts bin drawers. The coin envelopes I've seen were a little over an inch square AFAIR, and much thinner than Brown Kraft. But it was a very long time ago and in Europe.


Get the bigger ones, 2.5 x 4.25, so you can write lots of stuff on
them.


But then they take up more space and I can't get them into parts drawers. Usually I only keep 20-30 parts each, for fixing up a prototype etc.


They're so thin, there's hardly any volume. I bought a bunch of
plastic bins with lids, loaf-of-sliced-sourdough-bread size roughly,
and have one for caps, one for inductors, one for diodes, like that.
Mostly I just toss them in, although I keep intending to get
organized. You could use some plastic-tray drawer-organizer things and
order parts by value or something, if you're compulsively neat. My
office is directly over the company stockroom, with almost 2e6 parts
in stock, so I can just grab anything from stock. So the coin
envelopes in my office hols mostly samples, exotica, and stuff I use
often, like 0.33 uF caps and such.

Two of the bins are specially reserved, cookies and chocolate.

Really, the bigger envelopes are great, because you can write a lot of
stuff on them, measurement notes, mfr/part number, price, anything. I
tape the Digikey labels to the back, which just fits.

It's interesting how important this seems to be.


Yeah, you have a point there. I still got a 5-1/4 floppy storage case here, used for CDs right now. Occasionally they show up at a yard sale and the envelopes would fit into those. Maybe even into some 3-1/2" disk cabinets. One of the cabinets in the lab has 2-1/2" high drawers, maybe that would also work if I put them in sideways.
