Store small things like paper clips buttons etc. You can also use them to take a few days of a prescription on a trip. They will fit in your purse. You can roll thread around a folded piece of paper and carry a needle and a few buttons for and emergency sewing kit.
Using it for meds is ok, just as along they aren't narcotics. Narcotics must be stored in the container from the pharmacy. I was doing this too and should've known better (I'm a nurse) so I called my sheriff's dept. and they gave me the scoop.
