Surgical Stainless Steel 316 Silver Hook Earrings - 100 pieces (50 pairs) Surgical stainless steel material, relatively safe for those with allergies. These simple earring findings won't detract from your designs and will suit any style. Please use them in your handmade creations. I used to make accessories by hand. I have many items that I purchased but haven't used, so I will be listing them little by little. Although they are new and unused, they were taken out of their bags and stored in a case after purchase. Please consider purchasing, understanding that these are pre-owned items stored at home.
