Herobility Double Anti-Colic Baby Bottles are designed to provide comfort and convenience 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 ergonomically shaped teat closes the corners of the baby's mouth, and the air valves prevent a vacuum from forming inside the bottle. Made from BPA-free materials, these bottles are safe and easy to clean. The breast-like shape of the teat is accepted by 97% of babies, making feeding time easier. The bundle includes three bottles, each with a capacity of 8.5 fl oz/240ml, packaged in a hygienic bag made from recyclable plastic material.
