This is a set of two 160ml glass baby bottles and six nipples. The nipples are: SS x 2, S x 2, M x 2. Since I was exclusively breastfeeding, I barely used these. Also, they have been washed and sterilized, so the bottles themselves are in clean condition. The nipples have also been washed and sterilized, but because my child played with them once, there are some bite marks on two SS nipples and one M nipple (photos attached). - Brand: Pigeon - Quantity: 2 bottles - Included: 6 nipples - Capacity: 160ml - Material: Glass Please refrain from purchasing if you are concerned as these are used items. Thank you for looking.
