Microsoft Sculpt Bluetooth Mobile Keyboard for Windows 8

At less than three-quarters of an inch thick, the Sculpt Mobile Keyboard is both sleek and compact, making it great for people who are on the go. Plus the built-in Bluetooth wireless connectivity means there's no fussing with cords, cables, or transceivers.
The comfort curve keyboard is designed with a slight 6-degree angle in the keyset. This curvature helps to encourage a more natural arm and wrist posture, providing greater comfort during extended use.
