These transparent folders are easy to get papers into and out of without struggling to separate the front and back sheets as with the top-opening folders. Being able to see what is in each folder -- the transparency feature -- makes finding the "right" folder in a notebook easy. Each folder also holds several sheets of paper of many sizes. They are readily reusable which makes them even better. Post-its stick easily to the outside or inside for easy reference and updating. I would like to be able to buy a package with more than five at a time -- say 20 or 25 as an option to the five pack.
