These are good for their purpose...expanding to hold a large amount of paper. The most disappointing part is the price vs. amount. Four folders are right around $25 so if you plan on using a lot prepare to spend the money. Also when these do not come in their own box like other hanging folders but rather are packaged in plastic wrap so be sure to have an area set aside or extra boxes to store them if they aren't all going to be used right away.
I try to keep organized with hanging file folders but the standard folders only expand to about an inch and the bottoms are V shaped and never really never flatten out even if you crease them on the fold lines so my papers end up sticking out above the top of the hanging folder at the front and back. These hanging file folders look the same as the regular ones but expand to three inches. They have accordion sides so the bottom is flat. They are the solution to my problems. I don't know why I haven't seen these before. Definitely recommend them if you have the same problem.
