※The nipple will be sent attached, but as it is old, we recommend replacing it with a new one before use. This is a simple and easy-to-use baby bottle that allows your baby to drink like they would from their mother's breast without needing to change to a larger nipple. A container for paper cartons is also included. It's convenient for directly attaching to paper carton drinks like barley tea, juice, or Icleo formula, allowing your baby to drink from them! ● No need to change nipple size from newborn to weaning (comes with a Chuchu silicone rubber nipple) ● Cross-cut nipple hole controls milk flow based on sucking strength ● Easy-to-read bordered markings ● Sterilizable by boiling, chemical solution, or microwave ● All parts are safely made in Japan ● Bottle capacity: 150mL Please only purchase if you understand that this is a home-stored item.
