The rings are made from non-tarnishing, nickel-free electro plated steel, and measure a compact 1.2"/3 cm in diameter. The hoop is embellished with steel beads that enhance the weight and movement of the rings. Designed to comfortably attach to the nipple without the need to commit to body piercing, wearing is as easy as sliding the steel ring over the erect nipple and positioning in place. Squeeze the ring gently to ensure a secure fit with the tension keeping the ring in place.
