Kit includes hanging filing folders and interior folders for hassle-free filing. Interior folders are cut shorter than standard-size so they won't obscure hanging folders. Folders feature 1/3-cut tabs in assorted positions for quick access. Mix and match the assorted colors for different-colored interior files to avoid misfiling. Hanging file offers offer superior durability with poly laminate reinforcement strips across top edge and bottom fold. Hooks on both sides of the hanging files are designed to glide along guide rails. All folders are made of 11 point stock.
