Heavy-duty, expanding file with 12 pockets is made to resist everyday abuse and transport letter-size documents safely. Index dividers organize files into subcategories. File also includes an open top, extra-thick covers and rip-proof Tyvek reinforcement at gusset top and corners. Preprinted, double top tabs are aligned in a straight line for easy viewing. 1/3-cut tabs are preprinted with the names of the months from January to December for monthly indexing.
