Painfully pleasurable! These stainless steel Ultra Nipple Clamps are a fantastic way to explore nipple play as they are fully adjustable- allowing you to find the pressure that is most comfortable. Slip your nipple into the smooth hollow between the screws and slowly twist the steel balls until your desired sensation is achieved. The Ultra clamps are suitable for both pierced and un-pierced nipples, although the visual and sensual effect is heightened when the nipples are pierced. Ideal for both bondage beginners and BDSM lovers, these specially designed double screw clamps will not disappoint!
