The surface of the shell is not completely smooth. I would even call it amateurish "soft touch". So slightly rough, what makes pleasant and insensitive to scratches without the shell pretty flutschigen iPhone gives a significantly better grip.
The shell has under the usual recesses for Lightning, headphones and the mute slider. Lock button and the two volume keys are not left out, the shell has dedicated buttons integrated in the frame. The operation is thus easy because everything is easily accessible without having somewhere must reinbohren with your fingers.
