The Nipple Pump 10-Piece Set includes two nipple pumps with cylinder diameters of 0.28" and 0.43" (0.7 cm and 1.1 cm), and four nipple rings of different sizes. The nipple pump creates a vacuum effect, drawing blood into the nipple and causing it to become erect and more sensitive. Placing a nipple ring at the base of the nipple maintains this effect.
To use, start by choosing the appropriate nipple ring and pump for your nipple size and desired pressure. Load the nipple ring onto the pump, place the pump over the nipple and squeeze the bulb. After full erection has been achieved, roll the nipple ring onto the nipple and remove the pump.
