I have the I Phone 5, and since I have so bought a plastic sleeve that fits so great, that I no longer get off. Now I wanted a friend to give pleasure and so give him a protective cover, he has the I Phone 5S, Here the shell does not fit, they do not get it, it looks as if she is verkanntet. Now he has unfortunately thrown the packaging already gone, I can therefore not send back.
A closer look at the I Phone 5S, I noticed that the bottom is curved slightly, for this reason it does not fit the shell there.
The manufacturer should have the know, however, that the series of I Phone is not like the normal 5 he.
