Replacement or spare teat made in the UK for BORRN's bottles. Our bottles are Non-toxic as they're 100% sealed with a total silicone inner surface where no milk can be in contact with plastic. BORRN's soft and squishy silicone bottles are hard to put down. The silicone body has a unbreakable skin-like soft touch for your baby to squeeze and hold which is scratch and hit proof. With a 2-piece design it's easy to bring together even during sleepy nights. The breast-like teat has a super flexible nipple which moves and feel like skin to latch giving the best comfort for babies with an Anti-Colic DuoValve System that prevents bubbles forming and allows perfect milk flow.
