About silicone: Only certified biocompatible silicone is safe for body jewelry. To qualify as certified biocompatible, it must be approved by a regulatory body. For example the European Pharmacopoeia, Deutsches Arzneibuch, and U.S. Pharmacopoeia Plastics of Class V1. Biocompatible means silicone resists breaking down due to bodily fluids over time. If you don't have allergies, rubber is a-okay to wear! O-rings hold your jewelry in. For instance, they're used for tapers, retainers, plugs and tunnels with single or no flare. Just put them on close to the skin, and you're good to go! Our o-rings come in a range of sizes to meet all your jewelry needs.
