Hanging pockets are ideal for storing large amounts of paperwork for a single subject that needs to be frequently removed from the file drawer. The sturdy full-height gusset sides and bottom expand to hold up to 3-1/2" of letter-size material and keep papers from falling out when the file is being transported. Assorted pack includes one each: blue red standard green and yellow. Hanging pockets also include repositionable clear poly tabs for easy indexing.
