This is a Bluetooth wireless keyboard from iClever. It's a scissor-switch model with a numeric keypad and function keys. The dimensions are approximately 37cm wide x 12.5cm long x 1.5cm thick (at the thickest point), measured by hand. There may be some slight variations due to amateur measurement. Charging requires a USB-B cable. Please note that the cable is not included. I purchased it around 2019 and used it daily for about three months starting in March 2025. It is a working product that powers on, but the Enter key feels a little stiff (this may depend on individual perception). There are no other areas of concern. Please consider this item only if you understand that it is a used product. The box is not included, and it will be shipped after being packaged. Connection type: Wireless (Bluetooth) Key switch: Scissor Keyboard layout: Japanese
