Beautiful glass nipple suckers with elegant rubber squeeze bulbs printed with Fashionista flourishes. Includes 3 different size rings per pump. Slide the rubber ring over the glass cylinder, squeeze the bulb to suck the nipple into the cylinder, slide the black ring over the erect nipple and remove the nipple sucker for perfectly puckered nipples that stay erect with the help of the black rubber nipple ring. Or leave the suckers suspended and held in place by suction alone.
