Made from lightweight, BPA-free Tritan, Aiwibi Baby Bottle is shatterproof and durable. The breast-like soft silicone nipple minimizes air intake and nipple confusion, while vertical lines keep its shape. An advanced anti-colic system reduces bloating, and the inverted triangle vent valve ensures smooth, leak-free flow. With a unique handle for easy grip and a gravity ball design for 360°free suction, it includes a nipple brush and replacement nipple. Various nipple flow rates and bottle sizes allow the bottle to grow with baby.
