I have been using these folders for over twenty years for covers of my final engineering reports. They present well and look very professional at the same time. They are sturdy and hold up well. I like the interior pockets as they become a great place for me to insert an invoice or a extra item that pertains to the project but isn't a direct component of my report.
These folders were exactly what I needed for handouts to students. The quality is good and I like the dark blue color. The metal clasps are of good quality also and can easily hold my booklet of about 20 pages.
