Rechargeable touchpad. It's quite old, but there are no noticeable scratches. - Brand: Logicool - Model Name: Rechargeable Touchpad T650 - Features: Rechargeable, touchpad - Accessories: USB receiver - Size: Width: 133mm Length: 129mm Thickness: Front 7mm, Back 10mm I have confirmed that it works with a laptop installed with Windows 11. The confirmed operations are cursor movement, left click, right click, and drag using the built-in microswitches. Although I haven't confirmed the operation with dedicated software, I believe the basic functions are confirmed. Since it's old, I don't know the condition of the built-in battery. I sincerely apologize, but please understand that the battery life is not guaranteed. The items included are the touchpad itself, the included receiver, the original charging cable, and the outer box. Thank you.
