I use these folders in an elementary school library as the children's library cards and shelf markers. A shelf marker is what the students use to mark their place on the book shelf while they peruse the book to see if they want to read it to make sure it's a good fit to ask the teacher if they may check it out. So they are carried all around the school; they are pushed onto the shelves between books; they are scanned; they get a real workout! But I am still using some from last year. They last and last.
Started using Staples as our main office supplies provider. I found these folders to be cost effective and work well for organizing all of our business account and information. I do enjoy all of the colors that the folders come in now but I tend to lean towards saving a few dollars so I can purchase more items I need for our office.
