Good handling of the slides. However, the framework summarizes flap firmly so click that one small pin with a second opening (which is rare needed) often easily damaged. The slide, however, can easily insert. If you have this too tight on one side, it can still be easily pushed aside in order to use the other edge of the picture completely in the closed frame. Strong nails are needed when you are in short time frames on many slides. The slides bulge out in this framework and "popping" in the projector. Buenos Dias, love analog photographers!
