From the item description and photos, in my opinion it is clear enough that it is a very thin and open at the bottom plastic casing. This case protects the back of the iPhone from scratches. So first of all intended for those who want the iPhone almost unchanged, but a scratch protection Search. I would have just said to the critics who expected a shell that protects the iPhone from drops and the like. Just looking really read the item description, then you know also what you buy! The shell does so what they should. Mine was, however, scratched from the outset because it was probably already in a customer who has returned them. In my email to the manufacturer in this regard, I got down to the present day no answer. Last year I had sent this email. So the customer does not appear to be nonexistent. For this two star deduction. Also you should only invest once and be off until it is broken because my broke equal in weight loss because it so inflexible hard plastic. -
