****You'll be getting 1 container randomly picked by me. Just 1.**** I'm pretty sure it's brass, not entirely sure though. But look at the gorgeous patina! There is a stamp, a very little one, that says pat. 1919 on some of them. Measures 2 inches Would make an amazing steampunk pendant or accessory! It is partially segmented and joins at the bottom. Very easy to punch a hole in the bottom for wire wrapping. Can't hold any liquid though, it would come out. Plus it had lead in it at some point so no liquids.
