These clear tabbed folders are great for organizing different parts of a project all in a larger project folder. The see-through cover makes it easy to identify the contents and read the top page without opening the folder. I also use them to store all travel trip materials in one place. Again the clear cover allows me to see the current flight details or itinerary without opening. They are sturdy enough to reuse many times if you use removable labels.
I rarely buy plastic anything... but this is one item i love and am converting all of my paper household project and wish list tri-tab folders over to these and will probably never have to replace them. They take up less space than the paper ones and labels are optional as you can see what's inside. They're sealed on one side with the other side being open with a tab to keep it shut; which makes it easier to take out the papers as these don't accommodate too may sheets inside.
I use the clear & the multi-color poly file folders for files for handily see-through protective covers for documents when I travel or take to work...& many other uses. The covers can be used over & over - I usually don't write on them; instead I use stick on & write on subject tabs that can be removed & replaced. The plastic file folders hold up much longer than paper ones.
