With an iPhone 11 case, you can prevent bumps, scratches, and other damage. In addition to protecting the back, a book case also covers the 6.1-inch Liquid Retina display of your device. A back cover keeps your screen free, so you can always see your notifications right away. Do you occasionally drop your phone? Choose an extra sturdy iPhone 11 case with fall protection. All these iPhone 11 cases are made to measure and have cutouts for the dual camera, for example.
