Logitech 920-002555 MK550 Wireless Wave Keyboard & Mouse Combo

Logitech® Wireless Wave Combo MK550. A mouse-and-keyboard combo that gives you a comfort curve without the learning curve. The keyboard's Wave design with Constant Curve layout and cushioned palm rest guides hands into just the right position and conforms naturally to your fingers, helping you type with ease and confidence in a familiar layout. The mouse is a joy to hold-and use-thanks to the soft rubber side grips and laser tracking that's smooth and precise on just about any surface.* And your desktop is always ready with up to three years of battery life for the keyboard and two years for the mouse, and a tiny Logitech Unifying receiver that you can plug and forget.
