Microwave-safe baby bottle sterilizer, usable with 500-700W. - Brand: Combi - Notes: Microwave-safe, use with 500-700W - Internal structure: Includes a holder for baby bottles No instruction manual. This is a used item, so there are some water stains and scratches inside. Please understand. I used it a few times, but I am selling it because I switched to exclusive breastfeeding. It's easy to use and very convenient. It was convenient because I didn't have to buy more sterilizing solution. Thank you for looking.
