Everything "clear"

My daughter has a cell phone and had to be bought, of course, immediately obtain a protective film to do so. The order was simple, within 2 days, we received the delivery by letter. Applying the foil is very easy, if you take no towel to clean that boosts the display static. Then, there are problems with dust particles, resulting in unclean application of the film. Luckily only once happened with my son. Now the whole thing is somewhat protected.
