Review on 📸 DIGITNOW! 1 Pack - Spare 135 Slide Holder & 1 Pack - Spare 35mm Film Holder for Slide/Film Scanner (7200, 7200u, 120 Pro Scanners) by Kenneth Witte

It holds negatives very well, but if you bought it to scan negatives yourself you'll find that it can handle the film does not hold flat. Even to the naked eye there is a curve. If the edges of the plastic are too close to the edge of the image, not only will you lose the edge of the film (if you care), but the light will reflect off the edge of the plastic, effectively "chopping off" parts. of the negative.
