From NS Novelties' Bound collection, the C3 nipple clamps are a pair of butterfly (or clover) clamps offered in a choice of two gleaming finishes- Gunmetal and Rose Gold. The clamps squeeze open when pressure is applied to the sides, and spring closed on the desired body part. Round tips focus the pressure of the clamp to a small spot, creating an intense pinch, and stay in place thanks to grippy silicone pads. The butterfly clamp design means that pulling on the base forces the tips closer together, increasing the pressure on the skin. Each clamp is equipped with a small, swiveling snap hook dangling from the eyelet at its base, which allows the clamps to be attached to a weight, leash, or other equipment to create unique bondage situations.

The clamps are not adjustable, and are not attached, allowing for versatile use anywhere on the body. They are made from nickel-free iron.
