The new Classic+ bottle has only 4 parts for quick and simple assembly.
✅Unlike other bottles, the clinically proven anti-colic system is now integrated into the nipple, making it easier to assemble the bottle correctly. As your baby feeds, the unique valve on the nipple opens to allow air into the bottle instead of your baby's tummy.
With only 4 parts, a wide bottle neck, and rounded corners, our bottle is easy to clean quickly and thoroughly. Have peace of mind that your bottle is truly clean in no time." _________________________________________________________________________________
