The customized mouse pad covers 100% of the Arena surface and adheres tightly to the desktop with special materials. Arena Mouse Pad has a microfiber cloth surface which is water-resistant and machine washable. The mouse pad’s edges are stitched and the pad is 5 mm thick to maximize user comfort. Finally, the whole mouse pad weighs an impressive seven and an half pounds (3.4 kg) which together with the non-slip underside means it is impervious to any random movement over the surface.
