Resurrecting this thread:
I got a tub of Sandpaper yesterday (Probably a 10 year supply in addition to what I already have..) and wanted better storage. A search found this thread, and I stole Steveo's idea for the file box; Works great Steveo!

:
The score for $10:
After organization of the Sheet stock: -It took all the sleeves and there are 4 Pendaflex hanging folders, one for 60, one 800, one misc. full sheets, and one at the back with several packs of paper for a sheet rock sanding stick. The flat cardboard holders they sell 5 or so sheets in do NOT fit well, but the hanging folders do better than those things anyway, so I unloaded these and tossed the packaging. lastly I stuck some pre-cut sheets for sanders in vertically in front.
An earlier attempt (Amazon Box) that wasn't big or handy enough got diverted to Steel wool storage (this made me do a search and I found this thread. I was about to start a new one...):
The remainder consisting of rolled stick on disks for DA's and other pre-cut sheets went into the former resting place for my sleeve of sandpaper.
Anyone know what these pre-cut strips fit? 2-3/4" X 17", and there is a LOT of it...
