The back also provides a good non-slip grip and shows some of the pretty glass effect of my silver “x”

I'm also putting some faith in Silk that the rubberized back of the case will protect the glass back of the iPhone X as well as a case with a harder shelled back such as the Otterbox Symmetry might

Second, the design is quite nice: I chose the clear model, hoping I can see my phone’s gold back - and I can, and the grid design looks great (my guess is that it also helps protect the glass back by diffusing any pressure or blows).
