Thank you for viewing. I am selling an Elecom wireless trackball mouse with a red ball, designed for the left thumb. I was interested in it and bought it new last month, trying it out for a few days, but it doesn't suit me, so I'm selling it. I will send the main unit and accessories in the original box. [M-XT4DRBK-G] * Wireless trackball mouse * Left-handed / left thumb operation / red ball * Gaming-grade optical sensor * Dedicated software / 6-button function settings can be changed * New AA battery included * USB receiver included ※ Please refer to the internet for product information.
