I find these handy for attaching to keychain or carry on luggage. Holds a folded emergency $100 bill or a couple pills.
Works well for a pain pill holder, as well as a $50.
Not much to say except I am not disappointed.
This fits a $20 rolled up!
It's small. It's brass, it has the capability of holding things within itself. It's durable AF, and looks cool. I once used it to hold my hopes and dreams. I've lost them all, but I don't blame the capsule.
