The Sinful collection from NS Novelties is meant to bring playful kink items to a wider audience. The nickel-free anodized metal ring keeps the mouth open so wearers can breathe but not talk. The straps have a raised diamond pattern on them for decoration and the buckle closure means the piece is adjustable.
