This is a pigeon electric breast pump. I purchased it in January 2022 and used it about twice. After use, I sterilized it with Milton and stored it. I couldn't use it well... ★The baby bottle is made of plastic. I used only this bottle for about 4 months with milk. I sterilized it with Milton after each wash. There are water marks because I let it air dry. I took a picture of it separately in photo 4, but it didn't come out well. ★The nipple SS is not included because it was used! Please refrain from purchasing if you are concerned about hygiene. If you have any questions, please leave a comment. It costs over 10,000 yen if you buy it at the regular price☆
