This is the following set. ① Pigeon Electric Breast Pump ② Microwave Sterilization Case ③ 5 Bottle Nipples Regarding ① - Brand: Pigeon - Model Name: handy fit+ - Set Contents: Breast pump only. No baby bottles included. (As I am still using them for my baby) Includes instruction manual. Can be sterilized in the microwave. This is an item I bought for the first time for my second child, and although I used it for a short period, I was glad I bought it. Regarding ② You can microwave sterilize baby bottles and breast pumps by adding 50ml of water. The instruction manual is not included, but the usage instructions are written on the lid. Regarding ③ 2 SS size nipples and 3 M size nipples from "Mother's Milk" (母乳実感). Please note that the sizes and quantities differ from what is written on the box. I bought ① and ③ at a store for my child born in December 2024 and used them. I have been using ② since my older child, born in 2022. I no longer need them, so I hope someone can use them.
