Specifications:
* Dr. Browns bottles feature a patented two-piece internal vent system that works unlike any other bottle design.
* As the baby feeds, air is channeled from the nipple collar through the vent system, bypassing the breastmilk or formula, to the back of the bottle.
* Air never mixes with the breastmilk or formula which minimizes oxidation and helps maintain essential nutrients like vitamins C, A and E.
* 4 oz. Standard Polypropylene Bottle with Level 1 nipple, 3 pack, INDIVIDUALLY PACKAGED
