@Azariel91 So when did it become alright to harass people just you don't like what they say in the Lowe's? I hate that people take their dogs every damned place but chasing this woman around the store because she hurt your feelings is weak AF.
@stephchelim That looks like a clear silicone nipple shield used for breastfeeding. It fits over the nipple and areola to help a baby latch or to protect a sore or damaged nipple.
The rounded portion is where the nipple sits, and the wider thin silicone section rests against the breast.
