Unfortunately, this does not change the miserable quality of the film. Denounce special I want doing the backing sheet. This consists of 3 parts, each 1 sheet for the upper and lower glass surface and then the metal center. The sharp corners of the sheets tilt at Pocket, Protective etc. so that there can deposit dirt bringing the film dissolves after a very short time, or the film falls entirely on the slide in your pocket.
Within 2 months, I have lost several films in this way, simply because this said corners are too sharp.
The film for the front side is relatively good. This proves short use on already many scratches, thus looks fairly quickly from very old.
From my side a resounding no for this slide set.
