A sturdy, hard wearing 28 inch long nylon strap connects four tweezer style clamps. Each of the nipple and genital clamps have capped rubber ends and are individually adjustable thanks to metal sliders. Choose whether to opt for gentle or hard pressure or anything in-between. Can your genitals take more pressure than your nipples? NB. These clamps can be used by both men and women. Material: nylon, metal.
