Contour Design Optical Mouse
The Contour Design optical mouse for the right hand is an ergonomic design. Elongated buttons let you use the 
second knuckle of your finger to click, while a full-size third button is free for the double-click function. The Contour 
mouse has built-in arch support and a built in thumb rest. The result of the design is that it relieves pressure on the 
forearm, while reducing the amount of grip force required.
