Thank you for viewing! This is a set of Pigeon hospital-grade baby bottles, including 4 bottles of 100ml and 2 bottles of 200ml. Used for about a year. There is some staining. *For hygiene reasons, nipples are not included, but if you would like them, even though they are used, please let me know. (Sizes vary.) Please be sure to sterilize the bottles by boiling them after purchase and upon arrival.
