Microsoft Arc Touch Mouse - Black by Microsoft

Perfectly portable—and award-winning—Touch technology
Stylish and eye-grabbing, Arc Touch Mouse is more than a pretty device. It’s reliable wireless freedom plus Microsoft touch technology, on the go. Use it just about anywhere, even on a rough wood surface or carpet, thanks to BlueTrack Technology1. Plus, you can retain wireless control of your computer up to 30 feet away.

Curve it for use, flatten for storage
Arc Touch Mouse’s innovative design allows for quick use and storage. Curve it comfortably to get started. Then smoothly glide your finger up or down the touch strip. When you’re done, keep the tiny transceiver plugged into your computer’s USB port, or attach it magnetically onto the underside of the mouse. Then flatten Arc Touch Mouse to turn it off, and slip it into your pocket or bag as easily as a cell phone.
