Manufacturer: Pigeon ① Bottles for hospitals and maternity clinics (direct-attach type) 100ml: 3 bottles 200ml: 4 bottles Features: These are baby bottles often used in hospitals and maternity clinics. They are made of durable, easy-to-clean, heat-resistant glass. ② Nipples Manufacturer: Pigeon Product Name: Mother's Milk Realization Direct-Attach Nipple General: 2 pieces, Large Flow: 2 pieces ③ Caps Pigeon KR Cap, Yellow: 2 pieces ☆ Bottles, nipples, and caps can all be sterilized by boiling, chemical solution, or microwave. I purchased these because they were used at the maternity clinic, but I only used them a few times during the newborn period and have carefully stored them after washing. Please wash them again yourself after purchase, just to be safe. I think this is a good deal, as they cost over 3,000 yen each on Amazon. There are no noticeable scratches or stains, but please understand that these are used items before purchasing.
