Pigeon's Milk Feel Glass Bottle for Hospitals and Clinics, KR-100. It's 100ml with markings every 10ml. The nipple is likely the general newborn SS size. - Brand: Pigeon - Material: Glass - Condition: Used less than 5 times - Included: Direct-attach nipple Thank you for viewing. I received this at the hospital and used it a few times during the newborn period, then switched to exclusive breastfeeding, so I think it's in good condition. It has been washed with a bottle cleaner and sterilized.
