Looping around the peaks of the nipples, snugly positioning a breathtakingly powerful little vibrator under (or above) each, Evolved’s Vibrating Nipple Stimulators offer an overwhelmingly pleasurable level of versatility and toe-curling intensity to nipple play enthusiasts. Created to fit as precisely as possible, each nipple clamp features an adjustable design to capture even the smallest areas of nerve-ending rich nipple skin. The tightness of the grip can easily be adjusted with the screw pins. Once in place, push the button of each vibe to activate one of the seven vibration speeds. The vibes titillate and tease, and the subtle weight tugs and jiggles with any movement. Comes with the required batteries included.
