Updated: Replenishment, now [do not quite fit, a bit too long.] Fits

I have 5 attempts used up the first slide fit without bubbles.
Left and right is plenty of space, but there is not enough leeway in the length. This means that the film offends almost always at the bottom of the silver key and there forms a large bubble. You have quite snugly above, so that one does not get down to the button, which is unnecessarily difficult the film already. Had dei films 1-2mm shorter, they had the optimal size. Too bad.

==================
Today I received a replacement free of charge with new films that fit very well now.
There was a letter in which HandyNow apologized for the production error (incorrectly adjusted laser cutting of sheets) in the first film sets.
I think this is a very quick and simple complaints.
