Barrel Clamps get their name from the very distinctive cylindrical shaped portion of the clamp at the top. This barrel section is turned to either open or close the arms of the clamps. Because they are very adjustable, barrel clamps are great for beginners. Barrel clamps are made from steel and are either powder coated black or chrome plated. The tips of the clamps are covered with removable rubber sleeves to prevent injury to the nipples. The chrome plated steel chain connecting the clamps is 12 inches in length. <br /><br />Titillation with a touch of glamor! Nipple clamps can be applied to the nipples of either men or women. They create pain/pleasure by restricting blood flow from erect nipples by applying pressure to them. Most nipple clamps are adjustable allowing the user to determine the amount of pressure.
