Having worked as a record's managed years ago at a mid size law firm I've handled 100's of files encased in these types of maila file folders. So what is the difference between one or another. Thickness durability strong tab not easily worn out or bent For me a color system is not what I needed and letter rather than legal size fit the bill. Choice came down to Staples Manila File Folders Letter 3 Tab Assorted Position and certainly a 100/box would cover my current and future needs for some time. Assorted tab one can always backwards fold the right or left tabbed files to reverse what side a tab is on if necessary. This Staples brand was priced right and met the criteria I wanted in a manila folder.
