I picked up a couple of filing cabinets many years back for next to nothing. Use them to store all manner of things:
To list a few...........
Tools that don't go in the Craftsman tool chest
Tape - masking to black electrical to double sided
Gloves
Spare nuts, bolts, screws
Spray cleaners, penetrating spray, grease
Oil filters for grocery getters (purchase in bulk from Rockauto)
Auto electrical - wire, connectors, heat shrink
I find them very handy and always amazed at the amount of "stuff" one can throw in there.
Debated labeling each drawer, but I find I can open the right drawer 8 out of 10 times.
