Shotgun shell hat pin. Made from 12 gauge shotgun shells. This includes a pack of 10 hat pins in assorted colors. We have gold and silver pins. Each order will be packed with half of each. Manufacturers cannot be chosen as not all manufacturers will always be in stock. Colors: Gold and Silver Gauge: 12 GA Shell Manufacturer: Various Headstamps: Mixed 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. Please note: Colors will vary slightly as each gold and silver are not exactly the same.
