These nicely organized my binder. I wrote on tabs with Sharpy. Looks nice. Even able to 'erase' tabs with alcohol on a cotton swab! They seem durable enough especially for the price.
By maintaining a solid immovable presence in my binder these thick sheets of paper successfully kept individualized compartments of paper separate each section being designated by a color assume-ably in order of importance or value. I was relieved that the "good" paper would never touch the "bad" paper.
