A replaceable silicone gasket with an anti-shaped bottle for a S-SHAPE bottle. Anti-circular valve and holes in the bottom of the bottle effectively escort air from its interior and provide a constant flow of food, thanks to which the child can drink without interruption and without swallowing. The gasket was made of 100% high quality, hypoallergenic silicone intended for contact with food. We recommend replacing a silicone gasket every approximately 3-4 weeks with a frequent use of the bottle.
