Thank you for viewing! This is a Hello Kitty penlight. I bought it at Sanrio Puroland, but I don't remember how many years ago. It has an ON/OFF switch. You can switch between single-color illumination and color cycling with the button on the handle. (8 colors total) 【Size】 Length: 22cm Maximum width: 10cm I confirmed that all colors light up during operation. I haven't replaced the batteries. ☆This is a USED item, so please refrain from purchasing if you are concerned. ☆Shipping will be a simple method, wrapped in bubble wrap. Please understand. Feel free to ask any questions ✨️ Thank you for reading to the end!
