A case that easily sterilizes baby bottles using water. - Brand: Combi - Product Name: Baby Bottle Sterilizing Case - Function: Sterilizes with water only - Colors: White, Brown - Set Contents: Main unit, Instruction manual Thank you for viewing. I purchased this unused item from another person on Mercari, but I ended up buying baby bottles that cannot be sterilized in the microwave, so I am selling this. It seems the inner packaging has been discarded, but it has never been used. Please refrain from purchasing if you are concerned.
