The Belkin Premium Mouse Pad provides your mouse with a smoother surface ensuring greater accuracy, control, and faster response. Our hard laminate surface and neoprene nonslip backing keep your mouse on track and performing at its best.
On Amazon ($8.12 with prime) the size is listed as 10.4x8.46 inches (or 265x215 mm if that's how you roll)
It's a hard mouse pad (not cloth on top) for cheap. Just ordered one myself.
