Illuminated Mouse Pad with 4-Port USB Hub The Mousemat is the most deluxe mouse pad WE'VE ever seen. The curvy 11" x 8-7/8" rectangle has a trim clear-plastic frame with red LEDs in it, and (4) USB 1.0 ports on the long back edge for your peripheral convenience. Use the fifth USB port to plug in the included 43" long cord that connects to your computing device. Excellent mousing surface, and little rubber feet to keep it still.
