Protect your Kobo Aura (2nd Edition) with the Kobo Aura Sleep Cover Case Black. The sleep cover case protects your e-reader from scratches and damage. The magnetic closure makes it easy to open and close the case, which is very useful when you're on the go. When you close the case to put it in your bag, the auto wake/sleep function automatically turns off your e-reader. As soon as you want to use it again, you open the case and your e-reader automatically turns on again.
