First, in my pack, I had not 6 films 5. When more but I have to throw 2 (because the poses, although taking the usual system for all films is inexplicably difficult), in the end it I have a margin of 2 films. If this is due to the properties of a quality material, I'm willing to let bygones be bygones.
The instructions (in English but this is not a problem in my case) suggests that it is supposed to be included with the installation equipment. Result: I had to stock up a cloth and a "maroufleuse map" on older packs films. But again, I pass the sponge because they were not promised in the description.
That said, once the installation is complete, the result is quite satisfactory. See it on the length what it's worth.
