I have a package ordered with 3 slides and would also recommend to anyone so. The film must be very carefully prepared and centimeterweise slowly applied to the display using the enclosed small card. It should be practically no bubbles remain. I did that happen on the first try and the long bubble at the top of the display could not push away itself. Also at the second attempt with a new film could not be better. Again, the lack as the first attempt. Only the third / last slide now sits perfectly on the display and thus meets all expectations. I had repeated this kind of work performed, but have to work as precisely in any case.
