Nipple Pump

For permanently stiff nipples!
Two nipple pumps plus 8 securing rings in the set. Simply slide one of the rings over the opening of the pump and place the opening over the nipple. Then gently squeeze the pump ball - a sensation as if your partner is tenderly sucking on it! The vacuum causes the nipples to swell beautifully - and stay stiff when you slide the securing ring over the nipple. Nipple pumps with different opening diameters: approximately 0.7 cm and 1.1 cm. Securing rings in four different sizes: diameter of 2 x 0.5 cm, 0.7 cm, 1 cm, and 1.2 cm (slightly stretchable). 10-piece set.
