The image shows a pack of Dr. Brown's Natural Flow Narrow Level 1 Silicone Teats. These teats are designed for babies aged 0 months and up, offering a slow and consistent flow rate. They are made from soft, high-grade silicone and are compatible with Dr. Brown's narrow bottles, working with the internal vent system to help reduce colic, spit-up, and gas. The breast-like shape of the nipple encourages a proper latch for a more natural bottle-feeding experience. This specific pack contains two transparent silicone teats.
