This is for a slim-type baby bottle. I am selling it because I purchased it by mistake. The box has been opened, but the nipple has not been removed from its bag and is unused. Due to thickness restrictions, it will be shipped without the box or with the box folded. Thank you for your understanding. A size S nipple for slim-type baby bottles, usable from 0 months old. - Brand: Pigeon - Type: Slim type - Size: S - Age: From 0 months - Quantity: 1 piece Thank you for looking.
