One African Porcupine Quill & Brass Bullet Casing earrings. Matching brass hoops. As seen on Yellowstone, worn by Beth Dutton. We added the quills to spent .22LR brass bullet casings that we have collected, cleaned and polished. These earrings sure make a statement! They have been our most popular earring design since the inception of MergingMetals! Some porcupines have up to 30,000 quills on their body. Porcupines can't shoot out their quills, but they will be easily released when predators get it touch with animal. The quill tips have been sanded however they can still be sharp! Drop lengths with hoops measure approximately 4.0”. Choose from B. Light quills Quills may be all light in color or have pops of natural brown. *Quills have been obtain through legal measures, they were procured from deceased porcupines or quills that have fallen out naturally. We do not kill/injure/harm any porcupines for their quills.
