For hygiene reasons, nipples are not included. After each use, it was carefully cleaned and sterilized in a microwave. It was also sterilized after the last use, dried thoroughly, and stored in a Ziploc bag. There are some minor scratches from use, but I think it's in relatively clean condition. Please understand that this is a used item and has been stored at home. Oketani-shiki Direct Breastfeeding Training for Breast Milk Consultation Room 160ml (Glass) This bottle was recommended by the clinic where I gave birth, and I used a breastfeeding-real-feel bottle at first to help my baby develop sucking strength. The shape of the nipple is different from that of a regular bottle, and it allows the baby to suck in a shape closer to the breast. Because it is difficult to suck, the baby can take more time to drink the milk, which is easier to satisfy the baby. Since the manufacturer is Pigeon, you can replace it with a Pigeon bottle-type cap or replace the nipple and use it as a regular bottle. Thank you for viewing. Bulk purchase possible
