The Just in Case Lenovo Tab 4 10 Keyboard Cover Black lets you protect your Lenovo Tab 4 10 and allows you to start typing reports right away. Simply use Bluetooth to connect your tablet to the keyboard. Thanks to the wake/sleep function, you can unlock and lock the tablet by opening and closing the cover. The cover doesn't add unnecessary bulk to the tablet, so it's easy to carry it with you in your bag. You can also use the tablet to take photos when it's in the case, because the case has cutouts for the tablet's camera and buttons.
