Clear back means that it is transparent as it can be seen from the pictures.
I haven't dropped it yet and hope I would not drop it any time soon but I think it offers quite good falling protection.
It is not a cutout but a metal plate with brand logo and it is not on the back (can be seen from the picture).
Black would probably be nice with it.
Is the like clear plastic back slippery? Easily scratch able?
Can the case fold completely back (180°) on itself or just open like a book?
