Made of unibody anodized aluminum measuring less than 4 millimeters, the Thin Type Keyboard Cover protects your iPad Air without adding bulk, making it easy to slide your iPad Air into your purse, briefcase, or backpack. Smart sensing technology automatically turns the keyboard on when you need it & off when you don't, & function-specific keys provides shortcuts for copying & pasting text, adjusting volume, or playing music. In addition to that, autowake magnets wake up your iPad Air when you open the cover & put it to sleep when you close the cover, prolonging your tablet's battery life.
