Pigeon Nipple Bottle, Heat-Resistant Glass x 2 bottles 100ml 4 bottles or 200ml sets are also available, so please consult. ꕤ︎︎·͜· Pigeon Hospital and Maternity Clinic Bottle (Direct Attachment Type) KR-100 is a bottle often used in hospitals and maternity clinics, to which the Mother's Touch direct attachment nipple can be attached. It was really helpful in the early stages of newborns. I think it's something you only use for a short period, so I hope it can be of help to you.
