Set of 3 baby bottles, made of clear glass and plastic. - Brand: Pigeon ChuChu - Quantity: Set of 3 - Colors: Clear/Blue/Brown - Materials: Plastic/Glass - Sizes: Various sizes Thank you for viewing. Pigeon 240ml Glass Pigeon 160ml Plastic ChuChu 150ml Plastic Mother's Milk Realization Nipple SS size Please refrain from purchasing if you are concerned about used items. This is based on my personal assessment. The Pigeon 240ml glass bottle and the ChuChu bottle have clear markings. The ChuChu bottle has more markings below 50ml than the Pigeon bottle, which was very helpful during the newborn stage and when supplementing breast milk with formula! The Pigeon 160ml bottle was used frequently, and the markings are faded. I have used all of them with care ^ ^ Please feel free to ask any questions!
