The 25 folders lend themselves well to organizing scientific papers alphabetically. I used these in graduate school for this vary purpose. I know I can rely on them to last until my graduation due to their durability and construction.
We use hundreds of these folders throughout the year we archive them in boxes for long periods of time and they are very durable easy to file easy to label and incredibly useful to stay organized. These are the only hanging folders our company will use.
Ordered a box of 50 to organize a new file cabinet. The Smead hanging files were expertly packed are of very high quality and fit the file drawers perfectly. I could not be happier!
