Specialty Bottles & Jars is a company that sells glass , plastic and tin containers .
www.specialtybottle.com
They have several round tin containers from 1/2 oz. to 2 oz. with nice lids, one should be just the ticket
Check out their site...I use their tin cans with the screw on tops to store Ed's Red Bore Cleaner and other fluids that can eat wimpy plastic containers .
