Set of 4 glass baby bottles, 100ml each with graduations. These are direct-feed bottles. They are often used in maternity hospitals. - Brand: Pigeon - Quantity: Set of 4 - Material: Glass - Capacity: 100ml - Graduations: Yes Nipples are included, but they have been used and I am concerned about hygiene, so I will include them as a bonus if you would like them, please comment. Thank you for looking.
