This is a compact steam sterilizer that easily sterilizes baby bottles in the microwave. I purchased it around the beginning of March this year. I used it for about two months. The box and instruction manual are included. It's still clean and recommended for those who will be using it from now on. Thank you for your consideration. - Type: Microwave baby bottle sterilizer - Sterilization time: 3 minutes - Steam sterilization: Possible - Material: Plastic - Size: Compact Thank you for looking.
