This is a slim, compact wireless keyboard with a beautiful, single-piece appearance, measuring just 6.5mm at its thinnest point. This 2.4GHz wireless keyboard provides stable communication and comfortable operation. It uses a micro-receiver the size of a 1 yen coin, which is extremely compact and unobtrusive. No special driver installation is required; simply connect and you're ready to go. The key type uses a pantograph system, the same as a laptop keyboard, which allows for light keystrokes.
