These earrings are made with quills from Kemosabe, the prehensile tailed porcupine. He is covered in over 10,000 quills. The quills are just modified hairs that are barbed. But, unlike popular myth, Kemo cannot shoot his quills. If another animal came too close, he would jump towards it and any quills that made contact, would come loose and remain stuck in that animal. But since his quills are modified hair, they also naturally fall out and he can grow new ones. All the quills used in these earrings were collected over the years after they fell off him.
