As seen in Yellowstone on Beth Dutton. A pair of African porcupine quills are set in recycled .22 casings which hang from 1 1/2" antique brass hoops.  Sizes and patterns range as the quills are all natural.  Total length ranges between 3" - 4 1/2" long.  Porcupines shed their quills naturally so no porcupines were harmed in the making of our jewelry.
