Chuchu Baby Baby bottle & replacement nipple (1 piece). The baby bottle was used once for a trial, but I preferred another one and haven't used it since. The replacement nipple (1 piece) is new. The nipple is a type that can be used regardless of the baby's age, so size doesn't matter. To save on shipping costs, I will ship it without the box, and the box will be flattened and sent via Takkyubin Compact.
