I purchased this about a year ago and used it for about a month, but haven't used it since. Therefore, it's in a clean condition with no visible scratches or stains. There is no instruction manual, but after connecting to the power supply, align the lid with the logo on the box and close the lid to automatically start disinfection. The LED lamp on the top of the lid will blink slowly during disinfection. *＊*＊* ＊*＊* ＊*＊* ＊*＊* ＊*＊* JJOBO - Toy Disinfection Storage Box - 【Specifications】 ・Spacious 50L storage space that can hold plenty of toys ・Designed with rounded, smooth curves for child safety ・99.9% disinfection with approximately 1 hour of UV LED irradiation ・Can disinfect anything that fits inside, such as toys and stuffed animals ・Can also be used as a storage box after disinfection 【Set Contents】 Main body / Lid / Power adapter Size: Approximately 40cm x 40cm x 44cm (Inner dimensions: 38cm x 38cm x 35cm) Weight: Approximately 5kg Power supply: DC 9V / 1.4A Current consumption: 400mA Material: P.P Colors: 3 colors available Country of manufacture: Korea - Brand: JJOBI BOX - Color: Gray - Function: Disinfection by UV LED - Disinfection rate: 99.9% - Material: Compatible with various materials - Size: Can store multiple toys ※Please refrain from purchasing if you are sensitive to items stored by individuals.
