From NS Novelties' Bound collection, the M1 nipple clamps are two pairs of spherical magnets offered in a choice of two gleaming finishes- Gunmetal and Rose Gold. The spheres are drawn to one another by powerful magnetic force, and when placed on either side of a nipple or other piece of flesh, their tiny size focuses the pressure of the clamp to a small spot, creating an intense pinch.

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