Perific Dual Mouse

The Perific ergonomic mouse™ is several mice in one. Use it as a regular mouse or explore how you can gain a whole new range of ergonomic and practical benefits. Hold it any way you want. The smoothly sculpted grip-friendly design, and finger-free inner mouse leaves the choice up to you. The trackball frees you from the desktop and provides new ways of working.

• As a trackball on your desk

• Worn on the hand, for rapid but strain-free switching between mouse and keyboard
