Nipples are just like any part of the body, they can be “decorated”. Just like there is a hat on a hat, ring on finger, necklace on the neck, nipples can be decorated with fun and sexy nipple covers. There are 4 pairs of different design in one pack of above nipple cover. The designs are flower, heart, butterfly, and lips. However there are feedback that the Fun Pattern Beauty Nipple Covers are not sticky enough.
