Office supplies improve organization, communication and efficiency in the work place. They include writing implements such as ballpoint pens and markers. They also include clipboards and notebooks. Clipboards hold loose sheets of paper and provide a flat writing surface. They are ideal for mobile applications. Notebooks allow users to organize thoughts, ideas and notes. Some notebooks have perforated pages that make it easy to share or discard certain pages. Others, such as composition books, are more durable and are ideal for storing information over longer periods.
