BIBS Baby Glass Bottle is carefully designed for babies and parents. The bottle is made of borosilicate glass, which is temperature- and thermal shock-resistant, durable, emits no harmful substances into the milk, and much more. The nipple has been specially developed to match the nipple from the popular BIBS Colour pacifier and resembles the mother’s soft nipple. The nipple features an anti-colic valve, to ensure the best milk flow for your baby. The nipple is produced from natural rubber latex. The other parts are made in 100% food-grade material. Complies with the European Standard EN14350.
