Put these guides in place of file folders that are removed from a filing cabinet, as a reminder that the file folder is missing, and as a guide for where to put it when it is returned. They are made of extra-durable vinyl for heavy office use. Each features a center-cut tab with the word "out" printed on it. Use the 3" x 5" pocket for an index card or charge out slip. Each includes a diagonal pocket for materials that need to be filed in the missing file folder once it gets returned.
