With people spending more time using the computer mouse every day, an activity that leads to numbness and tingling of the wrist joint and muscles, the physical problem that comes with long-term usage has become more common. A new mouse pad with a special roll-up function is developed to solve this problem. When the wrist feels numbness and tingling after a long period of use, the tail part of the mouse pad can be rolled up into a soft mat to alleviate the discomfort. Otherwise, it can be flattened out as a normal mouse pad for normal use. This design adopts a simple nylon and buckle method that enables the mouse pad to be folded easily.
