Nipple Suction Bulb
The Nipple Bulb is equipped with a 2in/5cm Bulb for gentle pleasing pressure along with a clear tapered vacuum tube measuring 4in or 10.16cm. The tip diameter measures 0.39in or 1cm for comfort. Each bulb is accompanied by four erection O rings. Just apply to the nipple and squeeze for light, comfortable suction.
To use the erection O rings, slip ring on the vacuum tube before suction begins then slide off the tube onto the erect nipple.
