This is a Goros face bracelet (size M). I bought this about a year ago, but the size didn't fit me from the start. Recently, I've been working out, so it fits even less, and I'm selling it. * There are many scratches, and it's slightly oxidized/sulfurized. * Authenticity is difficult to determine with Goros, so please refrain from purchasing if you are concerned. * I need money, so I'm selling it cheap.
