Expanding file features an extra-long flap that folds down to create a sturdy base. Pockets expand on both top and bottom for greater storage than standard expanding files. Each pocket expands to a full 7/8". Two clear pockets on front have index card inserts for easy labeling. Expanding file is made of super durable, waterproof, tear-resistant polypropylene. File includes 12 clear indexed dividers, colored tab inserts printed with alphabetical and monthly headings, and a hook-and-loop closure.
