This package of sheet protectors replaced one I'd gotten from Staples ages ago so I had an opportunity to use an old one followed by a new one. MUCH better! Why? Because the old ones took about an hour and a half to get open to slide the paper in and then it was a chore to get it in there. The new ones have a little less friction so they open easily and the paper goes right in. Yes it also comes out more easily (make sure the opening is toward the top to keep them in) but the frustration level has dropped to zero.
This was purchased by a college student for a presentation as a part of a final exam. The sheet protectors are of excellent quality for anyone wanting to protect work from the weather elements. The higher cost over inferior knockoffs is worth it
