iPhone case with real maple wooden back. The case itself is black plastic with a satin finish, or clear plastic. It provides enough protection to the sides, but allows you to use the ports freely.
The back is real wood, so there is no case looking exactly like another one. Every piece is unique, because there is no tree looking exactly another one. Because of that, the case you get may be slightly different from the picture above.
Wood is a natural material, treat accordingly. If your phone doesn't like it, neither its case (hot temperature, too high humidity etc.)
