Use these folders to store materials in alphabetized notebook. Keeps info readily accessible because it can be moved around easily in these pockets and similar items stay together even the non-letter size housed in these clear color keepers. Could use these in more different colors so subjects could be stored by color as well which would require less info management.
I use these to save documents for work that I have to keep for many years. I had looked all over for them & finally found them at Staples. Yay Staples!!
