I was looking for a way to help get my classroom organized for my middle school students that would withstand their extreme lifestyles. I was tired of having them tear apart the metal and paper hanging folders. These seem to be almost resistant to thier abuse and the colors are cool as well.
The hanging slots were too small for my approx. 1/4 " round file cabinet metal rails. In contrast the Staples standard green(paper)type hanging file folders do fit.
