Two Pigeon baby bottles with yellow caps. - Brand: Pigeon - Quantity: 2 bottles - Cap Color: Yellow Thank you for viewing. These are Pigeon breastfeeding-real-feel direct-attach baby bottles, made of glass, for use in hospitals and maternity clinics. I am selling them because my baby's intake increased and I no longer need them. I used them once a day for one month. The bottle size is 100ml x 2, and the nipple type is for general newborns x 2.
