Some hardware does not need improving. The Naughty Pleasure Nipple Clamps are traditional clothespin-style steel joined by 11.5 inches of chain. Each clamp is 1.9 inches long and opens to half an inch, closing under fixed spring tension with no screw to adjust and no padding to soften the bite. They hold exactly as hard as they hold, every single time. Pull the chain to build pressure across both nipples at once, or let it hang and the weight keeps a slow steady pull going with your hands free. Steel and zinc alloy, nickel-free and phthalate-free, with enough mass to take a chill if you want cold metal in the mix. Clamp them on, pull the chain, and find out how much you actually like.
