Though I haven't had any in a long while, I'm a big fan of Altoids and went through a lot of tins. I've kept many of them for a long while, using some of them to hold board game components or the occasional desk bits.
But recently, as I was organizing my desk, I happened to find a stash of my tins. I found they stacked nice vertically (so they don't slide about) and the edge is just wide enough for a label (these printed from a brother P-touch labeler).
With all these (and room for a few more below the buttons), my desk drawer is so much neater and easier to find stuff.
NOTE: I used to store smaller batteries (AAA, AA, 9V, etc.) in these tins as well. Bad idea: don't do that. You could short the batteries. While unlikely to happen with most batteries, I opened one tin to find several AA batteries corroding, and another tin was actually warm because two 9V batteries inside were shorting, generating heat and swelling. So... no batteries!
