This is a sterilizer that easily sterilizes baby bottles in the microwave, along with a set of two 100ml Pigeon baby bottles. I bought these because Pigeon bottles of this size were used in many maternity hospitals. The sterilizer was used when I went back to my hometown, so it wasn't used very often and is in relatively good condition. - Brand: Combi - Product Name: Jokin Jo-zu α - Type: Microwave Sterilizer - Compatible Bottle Size: 130mm or more - Included: 2 baby bottles (Pigeon) Thank you for looking.
