A protective film in / out is also in the packet. I suggest using the back protective film before placing the hull to prevent colored traces (a fault almost all plastic shells), it makes the rear a little duller, but at least the buildup the shell is uniform. The fit is perfect, the holes are perfectly aligned with the buttons.
In summary, I am very satisfied with my purchase, quality and Ringke mark which in my humble opinion, still is a notch above Spigen.
