A useful little container that uses a screw cap from a soda bottle for a lid. I have successfully used both Pepsi and Coke lids so it is totally agnostic! I cleaned up some design artifacts from the original as well as adding thumb knurls on the rim, for a better grip, and a raised thin lip on the top for a better seal with the cap. We use these for tiny pill bottles that fit in a pocket and are secure. I add a bit of paper towel in the bottom for padding.
