The films are precisely minus about 1 mm each in width and height, which for lack of feasibility of a 100% accurate application is but sensible. The actual screen protector is also provided on the non-adhesive side with a protective film which can be removed after a successful application. The manual and the supplied "tool" (microfibre cloth and spatulas) are well suited for a flawless application.
Important: Before thoroughly screen and pay attention to halfway dust-free environment - then it will come without ugly or annoying inclusions.
