Create files within files for easy storage and access. Heavy-duty pressboard covers feature embedded two-prong fasteners on their interior face to keep top-hole-punched documents secure, and the front cover is also cut shorter to help the back cover's tab stand out, making both labeling and in-cabinet referencing easier. Heavyweight Kraft dividers feature embedded two-prong fasteners on both sides to simplify subdivisions. Scored spine expands to accommodate growing files and is reinforced with tear-resistant tape to withstand wear and tear.
