Sanwa Supply Mouse Table This is a mouse-only table that attaches to a desk's top with a clamp. The table surface is a mousepad. I bought this to make my slim desk, which I purchased for working from home, a little wider, but I couldn't install it due to the structure of my desk. Therefore, although it has been opened, it is unused. Please note that the assembly instructions are creased because I carelessly put them in the box. It is a clamp-type, which is installed by clamping and pressing the desk's top. I haven't even installed it, so I can't provide more information than what is written, so please search by the product name, etc. We cannot accept claims or returns due to inability to install on the desk, so please check the images and descriptions carefully and make sure you are satisfied before purchasing. The following is transcribed from the product box description: ■Size: W196✕D252✕H108mm ■Weight: Approximately 450g ■Compatible desks for installation: Desks with a top thickness of 17-40mm and a depth of 45mm ●By attaching the mouse table to the top of the desk, you can utilize the space on the desk more widely. ●The mousepad part uses hard PP, so smooth mouse operation is possible. ●Compatible with laser, optical, blue LED, and IR sensor mice ●Rotatable, can be stored under the top of the desk when not in use ●You can operate the mouse with your elbow at almost a right angle, so it is less tiring for your posture. ●Can be used on the right or left side
