Due to the fact that there are twice as many of the 5 tab end folders (2 on the right and 2 on the left) as there are middle tabs I always run out of middle tabs. I'd love to be able to buy only the 5 tab middle folders or see the pack have twice as many middle folders as are currently packed.
I like these heavyweight file folders. If you're going to be in and out of your paper files they hold up better than the regular versions of the file folders and stand up straighter in the hanging file folder holders.
