This is a Logitech wireless mouse. It came with the purchase of a PC. I used it once, but I am selling it because I am buying the mouse I was used to using before. There are some scratches, so please check the ○ marks in the photos. It works without any problems. Returns and exchanges are not possible. Please purchase only if you understand this. The Bluetooth-connected MX MASTER 2S combines comfortable operation and multiple functions. - Model Name: MX MASTER 2S - Connection: Bluetooth - Brand: logicool - Supported OS: Windows
