16G Body Piercing The ball part is gold, and the needle part is silver. There is no catch; it's the type that just hooks in, but it's long, so I don't think it will come off. I've worn it once or twice. I will disinfect it thoroughly before shipping, but please understand that it has been used, as it is something that is worn directly on the body. *Since it is 16G, the needle will not fit through a standard earring hole, please be aware.*
