Pigeon Mother's Milk Realization Baby Bottles ① Heat-resistant glass bottle 240ml x 1 ② Plastic bottle 240ml x 1 ③ Plastic bottle 160ml x 1 Chuchu Baby Bottle ④ Slim type heat-resistant glass bottle 150ml x 1 Set of 4, not sold separately. I used the 3 Pigeon bottles in rotation about twice a day for about a year. The Chuchu bottle was only used once. Nipples and cleaning tools are included. After each use, I washed them carefully and sterilized them in the microwave. The last time I used them, I sterilized them and dried them thoroughly before storing them in a Ziploc bag. There are minor scratches and water spots from use. Please understand that these are used items and have been stored at home.
