The K855 wireless keyboard with a Japanese layout uses alkaline batteries and offers comfortable typing. I even went to the trouble of adding cushioning material to prevent keyboard noise, but I only used it for 1-2 months because I replaced my computer. The original box is not available, so it will be shipped in a suitable box. - Brand: logi - Model: K855 - Battery type: Alkaline batteries - Connectivity: Wireless - Keyboard layout: Japanese layout Thank you for looking.
