Office paper and notebooks keep offices organized and on track. Business, expandable, and window envelopes are used for mailings and communication. Use loose-leaf paper, notebooks and writing pads, and tally and field books for taking notes. Sticky notes and flags are used to add comments to documents, point out changes on graphic layouts, and temporarily mark places of interest in the document for signing or reviewing. File folder and printable labels are used to identify file folder contents or for shipping or mailing tasks. Use index cards for recording information and taking notes.
