Stand out in these unique nipple clamps with LED lighting! The heart shaped adjustable clamps have a vinyl coating and are easy to attach to the nipple. By sliding the ring upwards you determine the desired intensity. You choose between the 3 different light patterns by pressing the center of the light. Press and hold the center for a little longer and the lights switch off. The light runs on batteries (included). You can not replace these but there are spare lights available.
