Microsoft Surface Touch Cover 2 - Black (Certified Refurbished);

Innovative, lightweight and just 2.5 mm thin, this revolutionary design just got even better.
Smart enough to know when you're deliberately pressing a key instead of just resting your hands, backlit, pressure-sensing keys also help you work in more places thanks to built-in illumination.
Fold the cover back like a magazine and keystrokes are automatically disabled to prevent accidental data input. Flip the cover back into keyboard position to return to typing mode.
The smooth, spill-resistant, easy-to-clean material repels moisture and dirt.
Navigate Windows easily with Windows shortcut keys. The built-in trackpad gives you the touch screen experience, without having to take your hands off the keyboard.
A magnetic connection without any buttons or locks to get in the way lets you instantly click in the Touch Cover - or simply pull it away to remove.
