Please see [Product Specifications] and [Product Description] for details. The EX-G is a 5-button mouse that achieves an unprecedented level of [ease of grip] thanks to its design born from the shape of the hand. It is a medium size that fits comfortably and securely in the hand. Focusing on the thumb and ring finger, which are used most frequently when operating a mouse, it is designed to conform to four points: the proximal phalanx, thenar eminence, middle phalanx, and metacarpal bone. The leather-like side grip on the side of the main body prevents the hand from slipping and enhances the sense of quality as a tool. Weight: Approximately 92g (including cable)
