Hello. This is a refresh accident prevention kit with a silicone coating. It fits almost all mask bands and is compatible with snorkel and regulator mouthpieces. This is a 5-piece refresh kit consisting of a new Mares strap holder, a new snorkel mouthpiece (with a tie wrap), a new goggle strap, and a new snorkel holder. It's all black, what do you think? This is a set of two.
