This is a wireless mouse from Logicool. It's a silent type mouse, so you don't have to worry about click sounds. I haven't used it much, so I think it's in good condition with no noticeable dirt or scratches, and the side grips are also clean. Operation has been confirmed. The batteries currently in it can still be used, so I will send it with them inside. There is no box or instruction manual, and everything in the photos is included.
