It sounds like you're describing a world map mouse pad that is 900mm x 300mm x 2mm in size, with stitched edges for durability. Here's a breakdown of what the description means:

• 900mm x 300mm: This is the size of the mouse pad. At 900mm (about 35.4 inches) in length and 300mm (about 11.8 inches) in width, it provides a large surface area for both mouse movement and keyboard space.

• 2mm thickness: The mouse pad has a moderate thickness, offering a comfortable surface for wrist support and a smooth glide for your mouse.

• Stitched edges: This feature ensures the mouse pad’s edges won’t fray over time, increasing the longevity of the pad and preventing wear and tear along the edges.

• World map design: The mouse pad likely features a detailed map of the world, which can be a great addition for those who like to travel, learn about geography, or simply enjoy the aesthetic of a world map on their desk.
