This is a Pigeon baby bottle that I purchased a little over two years ago and only used a few times for expressing breast milk. I think it's clean. I'm selling it to organize things for my move. It has been sterilized. Please understand that this item has been stored at home, so only purchase if you are okay with that. Immediate purchase without comments is welcome. As a bonus, I will include one nipple brush for cleaning. Please let me know if you don't need it. ※ I am also selling new, unused bottles of the same type and a sterilizing case, so I can offer a discount if you purchase them together.
