Colt Grips Wireless Vibrating Adjustable Nipple Clamps
California Exotic Novelties, LlcThese great nipple clamps are one of our favorites because they are small, vibrate and have adjustable tension. The vibrator is built into each clamp and activated with a simple push button on the end. A thumb screw lets you adjust just how hard you want them to clamp on to your nipples. They are made from durable ABS plastic that has a poly urethane coating that gives them a satin finish. They are waterproof so you can use them in the shower or tub also. Each one uses three watch batteries and it comes with twelve.
