The films come in a small plastic bag containing both films as well as a "cloth". A separate card for smooth is not bei.Diese but I have not really needed. The manual can be found on the back of the package and is written nice (not China translation)
I have the film only slightly removed from the base and then applied to the iPhone. Everything as described. After I had glued the first part of the film to the phone, the rest is moved by itself on the display and has stuck with no air bubbles there.
Highly recommend the film.
