Altoid containers do work well. I have one which I'm saving stems in. and noo I don't smoke stems. I'm just waiting for some breakthrough discovery which includes using stems for some way of getting high.

I prefer the pill bottle for my bud, altoid tins are kinda awkward and lumpy in my pockets where the pill bottle fits nicely, also tiny keef bitties collect on the cap, and thats always a nice suprise.
