Elecom Trackball Mouse Handy Type Relacon This is a one-handed mouse that connects via Bluetooth, making it convenient for operations like using it while lying down. I purchased it new and used it two or three times, but I ended up not using it because I didn't set up a theater system, so I'm offering it for sale to someone who can make good use of it. The retail price is 8,228 yen. #Mouse #Relacon #Bluetooth #PC #Smartphone #Projector #Theater #Gadget
