Sanwa Supply Wireless Ergonomic Mouse, Blue LED, 5 Buttons, Large, MA-ERGW8

This wireless blue LED mouse features an ergonomic design that keeps your wrist in a natural position. It's a wireless mouse that can be used without worrying about cables. It uses the 2.4GHz digital band, which is resistant to radio interference, and provides stable data communication over a wide range of 10m radius. It can be used by gently resting your hand on the side, reducing twisting of the wrist. It can be held at a natural angle, so it doesn't put strain on your wrist even when used for long periods of time. When you place your hand on the mouse, your fingers are naturally positioned to touch the left and right buttons.
