Office supplies help accomplish many tasks around the office. Office cleaning products help keep work areas clean and tidy. Pens, pencils, markers, and other stationary supplies are used to write down information and create eye-catching notices. Binders, clipboards, file folders, and file boxes keep office papers organized. Calendars and dry-erase boards help workers keep track of their schedules and projects. Copy paper and replacement ink cartridges refill printers and copiers when they run low.
