This is a set including three Pigeon baby bottles, one Chu Chu Baby bottle, nipples for baby bottles, a microwave sterilizer, sterilizing solution for baby bottles, and powdered milk. The Chu Chu Baby bottle and the second bottle from the left are plastic, while the two on the right are glass. The nipples include unused ones (pictured) of the Mother's Touch M Y-cut type, and all others are used. The slim type nipples (for the rightmost bottle) are available in S and M sizes. The microwave sterilizer is easy to use, requiring no sterilizing solution. The sterilizing solution comes in individual packets, making it convenient for travel. There are 27 packets. I used them not only for baby bottles but also for sterilizing toys. The powdered milk has an expiration date of December 2026. Please check the condition in the images. I gave birth a year ago, but I was exclusively breastfeeding by around 5 months, so I think the usage was minimal. Please note that the box for the M nipples and the sterilizing solution box have been torn or chewed by my child. No claims or returns are accepted.
