I purchased this new in May 2024. It cost around 3000 yen. I intended to use it for my child, but they were rushed to the emergency room immediately after birth and were exclusively breastfed, so I never used it and it has been stored away. It has been opened, but it is unused and has only been sterilized with Milton. For hygiene reasons, the nipple is not included. Please sterilize it again before use. This is a used item, so please refrain from purchasing if you are concerned.
