The wide neck bottle from nip® has an orthodontic shaped teat made of food contact silicone. The integrated anti-colic vent prevents air from being swallowed, thus reducing the risk of infant colics and the ACTIFLEX®-system prevents the teat from closing up, thus ensuring an even flow during feeding. The extra thick and perfect-fit flange ensures optimum non-drip fit on the bottle neck. The bottle has an additional Polypropylene (PP) sealing disc for a secure closure on the go. The body is heat-resistant and made of glass. To guarantee a constant quality, the nip bottle is BPA free and produced in Germany.
