Sexily stimulating nipples, clitorises and other particularly sensitive body bits, these power packed, suction based little vibes provide otherworldly pleasure with no cords or wires to get in the way.The Seduce Me Suckers are a good/great size, not too big and not too small, perfect for just about any nipple. Firm, velvety silicone scoops lend a tight seal, simply press the cup portion firmly over a nipple to activate suction. Unlike some similar toys, these hold tight and ultra secure- they'll stay precisely in place while buzzing and throbbing.Speaking of buzzing, that special sensation comes courtesy of a tiny bullet studded through the tip of each Sucker. One simple button at the side of the Sucker in question powers a steady tingle on and off.In body safe silicone, the Nipple Suckers clean easily using warm soapy water or a good toy care fluid/foam. Each vibe requires 3 LR754 batteries (included). * Each Vibrating Nipple Suck-Her is approximately 1.75 inches (4.4cm) in coverage
