Earring findings are made of the highest quality stainless steel 316L and they meet strict requirements for nickel, cadmium and lead content. Stainless steel fishooks, kidney hooks with or without an open loop and leverback hooks are very popular earring findings because of their hypoallergenic properties and the fact that even sensitive individuals tolerate them very well. We recommend using silicone earstuds to secure open earring hooks against loss.
