Backed by 60 years of research on baby’s natural suckling motion, our Flexible Slim Neck Nursing Bottles is so soft it flexes to the movements of babies’ mouth. Bending and stretching to the baby’s mouth movements. Air Ventilation System (AVS™) reduces intake of gas, a potential cause of colic.

Made from premium borosilicate glass material with excellent transparency and high heat resistance. Available in 2 sizes – 120ml (S size nipple) and 240ml (M size nipple).
