I purchased this on Mercari in January 2026. I used it once, but it didn't suit my child, so I'm selling it. The original blue bottle came with one nipple. The box of two nipples has had the film removed from the nipples, but they appear to be unused. I haven't used them, so I haven't checked the contents. Therefore, I will consider the nipples as unused. Regarding the baby bottle, I don't know the original frequency of use, but there are no noticeable scratches. Since it has been used once, I would like to sell it for a little less than the purchase price. Thank you. Chuchu Baby Bottle chuchu baby chuchu baby bottle chuchu nipple チュチュ nipple
