I love these file folders. I file business invoices in individual file folders so I use many of these. They are sturdy enough but not too bulky so many files fit in the file drawer.
Until I can initiate a scanning and electronic storage project I am using these folders to create new files for the coming year and also to store old files in banker boxes. They are very sturdy and are holding up well. What I really like about them is that the tab is wide and high enough to write a full description of the contents of the file folder due to having a larger label area.
