I bought two because I thought that for an extra 50 cents it's preferable to not have to pay for shipping again. It comes with two small cloths, one wet and one dry, with which you clean the screen, remove the protective film from the side where you will stick it, and place it. Even though I applied it by myself for the first time and it almost fit perfectly, there is a small line in one part that seems to have a little air. I don't know if it can be removed and reapplied if it is placed incorrectly. I believe that it is quite high-quality and protects the entire screen except for a small 2mm area around the edges, which I consider negligible.
