With a beautiful design that features a double strand of chain decorated with set cubic zirconia gemstones, this nipple clamp pair from the Sincerely, Sportsheets collection is equal parts glamorous jewellery and punitive BDSM gear. The clamps themselves are slim, tweezer-style clips, with rubber tips and a slider that is used to adjust the tension to the desired pinch. Once situated, their connecting chains dangle, pulling on the nipples with every movement and allowing both clamps to be tugged simultaneously- when they deserve it, of course.
