These simple and powerful nipple suckers are perfect for anyone looking for some consistent, strong suction. Place the base of the sucker firmly against the nipple to create a seal, and then twist the easy-grip control cap to create immediate suction. Enjoy a light sucking sensation or twist the knob further to create a serious vacuum. Just turn the cap backward to return the internal plunger to its original position and release the suction when you are ready. Made from ABS plastic.

Measurements: 4" overall length, 1.17" inner diameter
