This listing is for one PAIR of Gorilla Glass 16MM 5/8” real black obsidian concave martele double flare plugs. One side is the carved martele texture you see on one side and the other side is a gorgeous smooth concave finish. The flares are a bit larger at around 17mm. Oh boy, I really loved these so much although I hardly got to wear them. I ended up downsizing my ears significantly because having stretched ears was a hassle in my line of work. Hoping to find a good home for these beautiful plugs. Waited a good amount of time to get them made to order. Will sanitize them to the best of my ability before shipment.
