Pigeon Mother's Milk Realization Baby Bottles - Set of 5 (with 3 caps) Plastic, all 5 bottles are 160ml. The slightly slimmer type was convenient for carrying around. There are minor scratches, water stains that cannot be completely removed, and other dirt. Please understand this point before purchasing. All bottles have been sterilized, but we recommend washing and sterilizing them before use. We will include two bottles of Milk Pon, so please use them. For hygiene reasons, nipples are not included. I am also selling other baby bottles, so please consider purchasing them together!
