Slim, lightweight, and excellent for travel – the Surface Arc Mouse adapts to your hand and can be flattened for easy transport. The next generation of the best-selling Arc Touch Mouse offers many improvements, including touch surfaces for vertical and horizontal scrolling. The design of the Arc Mouse is focused entirely on comfort and intuitive handling. It powers on when opened into the curved position and turns off when flattened. The sleek and lightweight Surface Arc Mouse weighs less and is thinner than a standard mouse, making it ideal for on-the-go use. When flattened, it easily fits into any bag.
