I bought a similar product from a competitor and they were horrible! These are easy to use the slide is easy to put on and off regardless of the thickness of the report.
I use these for handouts at presentations; they hold enough pages and allow our glossy brochure to show thru the cover. I can update them by taking them apart whenever necessary (which I have done on several occasions). Good value for the price.
I was very disappointed. It was frustrating trying to open each report cover. Could not even tell which side was which causing more time to put reports together. Side closures difficult to place on covers. Not normally disappointed in Staples brands but will not buy these again.
I've used these for four years to present my tour packages. They make a great appearance at a nominal cost. The only problem I have is that sometimes it is difficult to slide the closure on. It is supposed to handle up 20 pages...I had 15 and would find 20 to be very tight.
