A computer mouse pad comprises a rigid base and a plurality of fanfolded paper sheets arranged in a stack and detachably fixed to the base. Each of the stacked sheet is detachably fixed to a sheet immediately below it in the stack through microperfs. A subtle opening and closing of two levels of paper at the fold where two perfs occur, induced by mouse pressure, endows the working ply surface with a flexibility of vertical movement, creating a subtle mouse buoyancy. The sheets are provided with printed messages on upper surfaces thereof. A coating is applied to the upper surfaces of the sheets. The coated upper surfaces are resistant to being written upon, thereby preventing accumulation of carbon, graphite and ink markings, which tend to contaminate the roller ball, prevent proper mouse tracking and adversely affect curser control. When worn, the uppermost sheet is removed by tearing along the microperfs, thereby exposing the next sheet in the stack and its message, for use as the upper surface of the mouse pad. Timely refreshment of the upper surface may be encouraged by provision of a mouse pad in which the information conveyed by successive sheet removal creates a serial effect.
