Two 180ml PPSU bottle sets in a box. Each set includes bottle, cap, anti colic teat 0-3 mth old and teat cap. You get two complete bottle sets in your pack. We love our PPSU bottle and ANTI COLIC teat. What is PPSU - it is a new healthier, safer bottle because it's made from an amber tinted PPSU plastic, a healthier plastic that doesn't leach nasties into your warmed milk like normal clear plastic does when it is heated. We include one PPSU bottle also with your Tiny Bloom breast pump. You can pump directly into your bottle. 180ml capacity Universal sized teats fit our bottles - great news for when or if you require a different flow for older feeding.
