Very easy to use and can hold up to 1.5" of documents. We use these to file all the papers for our business. Easy to label re-label and even re-label again!
I use my manila file folders to organize my plethora of personal documents and also data I use for peer advocacy. They are extremely easy to label especially with a Sharpie. They last forever. The last time I had to buy a box of folders was approximately 10 years ago. I am just now using the last of them. I expect this box to last a comparable time. And what a deal!
