The iPhone can be easily insert into the shell. Since the shell is really very thin (about 1 mm) and light iPhone is also nearly as thin or inelegant. On the contrary, the shell looks good and high quality and feels like that. In addition, it is now well protected from minor bumps or scratches on the back. The only drawback are the keys which are through the envelope a lot more difficult to push. For the price but you can hardly expect more.
