Herobility Double Anti-Colic Baby Bottles are designed to provide comfort and ease for both babies and parents. Developed by parents and approved by babies, these bottles feature a unique double anti-colic system that prevents air from being swallowed by the baby, reducing colic and discomfort. The bottles are made from safe, BPA-free materials and come in a pack of four with assorted colors: Denim, Black, Dusky Green, and Gray. Each bottle has a capacity of 5 fluid ounces (140 ml) and includes a vented teat that mimics the breast shape, making it easier for babies to accept. The ergonomic design ensures easy handling and cleaning, making these bottles a practical choice for everyday use.
