Thank you for viewing. This is a set of two 160ml Pigeon Breastfeeding Realization bottles, one glass and one plastic (nipples not included). The markings on the glass bottle are slightly smudged, but you can still measure accurately. I have sterilized and washed them, and stored them, but since they have been stored by a non-professional, I recommend sterilizing them again before use. I have a cat, so please refrain from purchasing if you have allergies or are concerned. Pigeon Breastfeeding Realization Baby bottle
