Suitable Standard: TS EN 14350 Recommended Age Range: 6 months + Features: Mamajoo PES * In the production process of baby bottles, by keeping the health of the baby in the foreground, the highest quality raw materials in accordance with European Union standards and the latest technology were used. Mamajoo Baby Bottles can be easily sterilized in the sterilization device since they do not have small parts. The unit of measure on it is found in both ml and oz; clear marks ensure exact measurement and ensure how much the baby is fed. The bottle cap completely covers the bottle nipple and allows for travel without leaking. About PES: PES (PoliEterSulfon) material, unlike other plastic bottles, does not decompose molecules and does not contain BPA material, which is not suitable for your baby's health, even when exposed to very hot water. Functions: The wide-mouthed bottle is easy to fill and clean. It does not tip over easily thanks to its wide base. Ergonomic grip curves are designed to hold tiny hands easily and to support muscle development. The bottle nipple, which is presented in the form closest to the mother's breast, stretches thanks to the augers on it. It makes it easy to combine breast milk and bottle feeding thanks to the flavorless odorless silicone teat. The anti colic valve in the bottle nipple helps prevent babies from swallowing air during feeding. There are 3 types of bottle nipples with different fluid flows, suitable for the development and need of babies for use with the bottle. Package includes: 1 bottle and bottle nipple.
