This is a listing for a set of two ChuChu baby bottles. Left: Plastic, 240ml Right: Glass, 160ml I used these in conjunction with other baby bottles, but I'm selling them now as I've been using them less. I started using them about a month ago. There are no noticeable stains, but there may be some minor scratches from use. The nipples are less than a month old. I will ship them attached unless you prefer otherwise. If you don't need them, please let me know. Please understand that these are used items from a private seller.
