Not for the faint of heartIf you are into nipple play, buy these. Thank me later. Man or woman, whatever your nipple shape may be. these are easy to apply and adjust to achieve just the right degree of nipple pressure. Pull on them when clamped down to enhance the experience.Great quality they say these are for women but men can easily use them also they tighten up just perfectly and stay onGreat weight and adjustability. Clean finish. Teeth of clamp heads can apple as much or as little pain as desired.
