The BeanStalk baby bottle is a 150ml bottle made of Tritan, which is lightweight and highly impact-resistant. - Brand: BeanStalk - Capacity: 150ml - Material: Tritan - Country of Manufacture: Japan I purchased this because I was having trouble with my baby refusing bottles. I used the chuchu bottle once, but the baby wouldn't drink from it, so I sterilized it and stored it. The BeanStalk bottle is new and unused. Both bottles come with nipples that can be used from newborn to weaning. Thank you for looking. Please comment if you have any questions.
