3-WAY Baby Bottle Sterilizer Case Size: Approximately 20cm x 20cm x 10cm Purchase Date: Around November 2022 Thank you for viewing! I used this for about 2 years with my eldest and second sons. It functions as a chemical sterilizer, microwave sterilizer, and storage case. I washed and stored it after use. There are no noticeable scratches or stains. There is no instruction manual. Please refer to the official website for instructions: https://www.lec-online.com/c/03babykids/4903320047921 The following is a product description: ● With the new "Easy Drain Basket" function, you can easily take out the baby bottles without touching them directly, shortening the time it takes to sterilize them. ● There is no need to take them out with troublesome and difficult-to-use tongs. Because it is a drain basket type, you can dry it with the basket without touching it with your hands. ● For microwave sterilization, just pour water with the included measuring cup. You can microwave it and dry it with the basket without touching it with your hands, making it hygienic. ● For chemical sterilization, it comes with a lid that allows the items to be fully submerged. It has markings for 1L, 2L, and 3L. ● Since you sterilize the items with the case, you can use it as a clean storage case for baby bottles and other items. ● It can be used to sterilize (disinfect) not only baby bottles but also pacifiers, mugs, cups, and breast pumps. ● Can be used in a microwave with an output of 500W~700W. ● You can sterilize 3 sets of baby bottles, nipples, caps, and hoods at once (depending on the size, 3 sets may not fit). Thank you for viewing. Thank you very much.
