This is a set of three Pigeon baby bottles. I am selling them because I switched to 240ml bottles as my baby grew. They were used for about two months. I washed and sterilized them with steam after each use. The materials and nipple sizes are mixed, so please refer to the following: - Brand: Pigeon - Capacity: 160ml - Material: Plastic x 2, Glass x 1 - Nipple Size: S x 2, M x 1 Please understand that these are used items, so please refrain from purchasing if you are not comfortable with that.
