Thank you for viewing. ※Nipple is not included. Used only during the newborn period. Made of glass, it is durable and has no noticeable scratches or stains. I think it's in relatively good condition, but please be aware that it has been used by a child. [From the product page] A baby bottle that supports breastfeeding. Because the baby can drink with the same mouth movements as when drinking from the mother's breast, it is easy to use in conjunction with breastfeeding and smoothly assists breastfeeding. The gentle, rounded bottle is easy to hold and support, and is designed to not roll easily. It is a wide-mouth type that is easy to wash and prepare formula. Made of heat-resistant glass.
