316L Surgical steel in a 16G threadless labret with 4mm flat back in 16G 8mm with a pretty heart top with progressive CZ sized gems lining the edge. Heart top is approx 7mm and is made from steel and brass pvd plated when colored.
Because brass contains copper, it can oxidize with moisture or skin chemistry and leave a harmless greenish tint on the skin. It isn’t an allergic reaction, but it does make these pieces better suited for occasional or event wear rather than daily use.
