These tweezer nipple clamps are great for beginners and advanced users alike. The pain threshold from these tweezer nipple clamps are adjusted by a sliding ring. The sliding ring allows you to have them on very loosely to very tight. Specifications: The clamps are about 3 inches long. The chain is 12 inches long. The overall length is about 18 inches.
Review Of CNVXR-ST185, June 30, 2008 This was an experiment for me, the first clamps Ive purchased. They feel great when theyre on, but I find that the ring that slides to adjust the pressure tends to slip, and that they fall off.
