Fresh Tweezer Nipple Clamps purple. Nipple Clamps Beaded. Beaded nipple clamps can be applied to the nipples of either men or women. Beaded clamps are more often used as nipple adornments rather than traditional clamps which are used to create pain/pleasure by restricting the blood flow from erect nipples by applying pressure to them. Most PHS International beaded clamps are made with tweezer clamps. Tweezer clamps are attached to the nipple by slowly sliding a small bar up the tweezer. They can be worn very loosely and without a lot of pressure applied to the nipple. Made using phthalate free, non-toxic materials: metal tweezers, tipped in black rubber for added pleasure.
