It is a shell! The thickness of the stuff is awesome, and really reassures the screen will be protected even if you scratch the Spontex. The protection will be fucked up, but see what to do for damaging it. Adaptation is perfect, the so obvious product in poses that does not need to read the operating instructions unless you are German. Very good product, and indispensable at that. The price is not stolen, it's good Delamax.
