The films are extremely stiff and thick. Sometimes it makes sense to raise and foil with tesafilm hair or dust to entfernen.fehlanzeige in the film. I had on the side opposite the press sheet so that they curl up. Unfortunately, it is now so broken that I have 2 projecting corners. So either free of dirt or kinks and waves at the corners.
Furthermore bothers me is that the top sheet does not include the black border.
I have such problems never mumbi mobile films had, so I write it times the slides.
