The 3M Precise Mousing Surface is the only mousing surface designed to enhance the performance of your mouse. The 3M precise mousing surface is specifically engineered to eliminate all the frustrations related to the common mouse pad. Everything from its unique shape and ultra-thin profile to its microstructured surface has been developed and refined by extensive real-world testing and use. This new mousing surface is designed to conform to the way you work (not the other way around). It's simply the most advanced, high-performance mousing surface available. And now that it's here, conventional mouse pads are obsolete. So, how is the 3M precise mousing surface different? It's not square, with rounded edges. Instead, it's uniquely shaped to match the movements of your hand. It contains no bulky, spongy foam; actually, it's barely thicker than a piece of paper. And the surface isn't all slippery like foam mouse pads; rather, it's textured to hold and precisely guide the trackball of your mouse. The 3M precise mousing surface. It's the biggest improvement in computer mousing technology since - well, since the mouse itself!
