This pair of fully adjustable vibrating nipple clamps provides hands-free stimulation to one of the body's most sensitive areas. These clamps apply a constant amount of pressure to the nipples and swing as you move which provides you with even more sensation as they pull on your nipples. Simply adjust the vibrations to the appropriate level for you using the dial at the bottom of the clamps. The rubber tips also add a feeling of comfort. Powerful yet quiet, these nipple clamps are also lightweight and can be used by men or women. Free batteries included.
