A single African Porcupine quill is set in a cast bezel fashioned after a recycled .22 casing and hangs from a 32" antique brass curb chain. Simply put the quill through the end of necklace and adjust to fit. Quill sizes and colors vary as they are all natural. Porcupines shed their quills naturally so no porcupines were harmed in the making of our jewelry.
