Brand new, unused. I bought this for use in case of a disaster, but I'm selling it because my child graduated from baby bottles without ever using it. Please refer to the photos of the box for details. Purchased in 2022. It has a 5-year quality guarantee, but it seems it can still be used after 5 years if sterilized. Please use at your own risk. Also, please consider this only if you understand that it has been stored by a private individual.
