These heavy-duty Nipple Weights will leave your nipples perking with pleasure! Each classic alligator-style clamp is attached to a round metal weight that features grooves at the bottom. Simply attach more weight by screwing the additional weights onto the bottom grooves and enjoy the extra pull. Train your tits to endure the pain and gradually work your way up to more weight--the more often you play, the more weight they'll be able to handle. The adjustable screws allow you to modify the amount of pressure on the nipple, while the soft rubber lining helps ease the pinch.Each weight weighs 1.25 oz, each fully assembled nipple clamp weighs 4.25 oz.
