Address common breastfeeding issues: Our nipple shields are designed to help with flat or inverted nipples, as well as difficulty with breastfeeding, pain, and overproduction. Safe and comfortable material: Made of 100% clear, food-grade soft silicone, our nipple shields are ultra-soft, lightweight, and resilient. They're also BPA-free and non-toxic. Innovative design: Our nipple shields feature a split design with a removable built-in valve and longer nipples, making it easier for your baby to get milk while reducing your pain. Secure fit: The built-in valve fully wraps around the nipple, so you don't have to worry about your baby pulling it off. The airtight negative pressure design means the more your baby pulls, the tighter the fit. Natural feel: Our nipple shields have a petal design that conforms to your body's curves, making them easier to fix in place. The imitation areola bump design also ensures that your baby and the nipple shield feel more realistic and natural.Products from LUOLV's store
