The SteelSeries QcK-line of mouse pads are made of high quality cloth material, providing a precise and consistent glide. All mouse pads feature a specially designed non-slip rubber base which prevents the pads from sliding, no matter what surface the mouse pad is placed on. The mouse pads differ in dimensions and thickness, but not in precision, glide or quality. As some of the mouse pads are very large, we highly recommend measuring how much space you have on your desktop before ordering.- Ideal for low sensitivity mouse settings- Compatible with all mice- Specially designed non-slip rubber base- Dimensions: 320mm x 270mm x 2mm
