Tweezer Nipple Clamps
These all classic Tweezer nipple clamps cannot be missed in any good tit torture collection, so of course: also available @ Mister B s.
Each clamp consists out of two little metal rods, each one being capped by a soft plastic protector. You close the jaws of these clamps by shoving the little black plastic rubber rings towards the opening. By doing so, you also gradually increase the squeeze of these clamps, allowing you to customize the pressure to the pleasure / pain threshold of the wearer.
