Fastener folders are an excellent solution to subdivide papers inside a folder and make it easy to keep paperwork in sequential order for frequent reference. The addition of a pre-installed divider with fasteners lets you store information under four separate filing surfaces within a single folder. Shelf-Master reinforced tab gives added strength where you need it most. End tab is straight cut. The four fasteners are 2B style. Folders are made of 11 point stock.
