Nipple Pump

For long-lasting hard nipples! Two nipple pumps with 8 replacement rings. Just slip one of the rings over the pump´s opening and then place the opening onto your nipples. Then squeeze the pump ball. It will feel as if your partner is gently sucking them! The nipples become wonderfully erect, thanks to the vacuum and they also stay erect if you put the fixation rings around the nipples. Nipple pump with openings that have various diameters: 0.7 cm and 1.1 cm. Fixation rings in four different sizes: diameter 2 x 0.5 cm, 0.7 cm, 1 cm and 1.2 cm (slightly flexible). 10-piece set.
