Shotgun shell hat pin. Made from 12 gauge shotgun shells. The shotgun shell head slices have been rough cut with the primer still intact. Slices have not been cleaned or polished. Each pin is approximately 2.4-3.8 mm thick (not including the pin). They will vary slightly slice to slice. Approximate diameter is 22mm. Each bullet has been fired so expect some normal wear/marks from the firing process. The back fastener is a metal butterfly back.
Made in the USA
