This is a sterilizing and warming kit for baby bottles and liquid formula. With just a small amount of water, you can easily sterilize baby bottles and warm liquid formula anytime, anywhere. You no longer need to carry around a lot of feeding supplies and spare baby bottles, allowing you to enjoy outings with your baby more actively. The steam core (heating agent) expiration date is August 2028. There are 29 remaining. I used it when I went back to my parents' house. It was surprisingly easy to use, and it was convenient because all I needed was water. The regular price is about 9800 yen. #BabyBottle #Warming #Sterilizing #DisasterPreparedness #Travel #FormulaFed #BabySupplies
