Gently used anti colic infant baby bottles 4(5oz) 3(8oz) Includes lids, mixer inserts and nipple collars. My personal opinion is these are the BEST bottle for a tiny new baby with latch issues and reflux. They also DONT LEAKKKK like all other bottles! NO NIPPLES are in this set. They can be purchased on Amazon or Herobility.com! Each bottle costs around 10-6 dollars a piece originally plus the shipping costs. This is a huge STEAL!! Designed in Sweden 🇸🇪 ♥️ Gentle flow speed thanks to its breast-like shaped nipple. ♥️ Ergonomic anti-colic teat accepted by 97% of babies - ask for our live survey! ♥️ Few parts and a wide opening make it easy to clean. ♥️ Leak-proof. ♥️ FDA-approved materials.
