This is a glass baby bottle from Pigeon's Breastfeeding Consultation Room. It's a set of 3. I've used them a few times. The nipples are also included in the photos, but please let me know when you purchase if you don't need them. I don't think the nipples in the photos are usable, so please purchase new ones separately! There are some minor scratches, and they have been stored at home for a long time, so thank you for your understanding. ■Product Name: Pigeon Breastfeeding Consultation Room Baby Bottle ■Capacity: 160ml ■Nipple Size: SS (for newborns) ■Type: Glass ■Condition: Used a few times This is a baby bottle specifically for the popular "Okedani-style Breastfeeding Consultation Room" to support breastfeeding.
