This early Apple mousepad matches the beige plastics of the original Macintosh used from 1984 to approximately 1990 (Apple changed the Macintosh to to Platinum in 1990). The mousepad measures 8.5 x 11 inches with rounded edges and is 3/16 inch (0.1875) thick.
The mouse surface is a textured plastic that is showing some discoloring due to its age. It features a classic Apple multicolor logo in the lower-right corner. The bottom of the mousepad uses a rubber textured material.
