These ultra-soft silicone seals, which fit like a second skin, help your baby during breastfeeding when the nipple skin is cracked or irritated. These TOMMEE TIPPEE seals come with a convenient box that allows you to sterilize them in the microwave while maintaining hygiene. They adapt to the breast and stretch with the movement of the nipple, enabling maximum contact with the baby. Easy to use: milk flows well through three holes, so you won't have any issues while breastfeeding. It does not prevent the baby from experiencing skin contact and the scent of their mother. The handy box makes it easy to transport these seals hygienically and take them anywhere. Safe for the baby: made from odorless and tasteless, soft and thin silicone. It allows for air circulation, making it safe for the skin. Contains no BPA. Suitable for breasts of all sizes. Set includes: 2 pieces + practical box for sterilization and storage.
