This is a set of baby bottles. - Brands: Pigeon (glass 200ml, 120ml x 2, 100ml x 3) (plastic 240ml x 2), NUX (plastic 250ml x 2), chuchu (glass 150ml) - Features: With measurement markings - Accessories: Nipples are only the original sizes. I believe M size nipples were originally included with the 240ml bottles and larger. Please consider the nipples as a bonus. They have been sterilized, but please refrain from purchasing if you are overly concerned about cleanliness. Thank you for looking.
