Used for about a month from May 2025. Disinfected after each use. Although disinfected, please consider only if you understand that these are used items. Pigeon Nipple Bottle, Heat-Resistant Glass (100ml) x 2 Please purchase nipples separately. The Pigeon Hospital/Maternity Clinic Bottle (Direct Attachment Type) KR-100 is a bottle often used in hospitals and maternity clinics, and can be used with the Mother's Touch direct attachment nipple. In the early stages of a newborn, they only drink a small amount of milk and need to be fed frequently, every 3 hours. There were times when I couldn't keep up with washing, so it was really helpful. I think you will only use it for a short period, so I hope it can be of use to you. Only for those who understand that these are used items. Thank you.
