Writing material refers to the materials that provide the surfaces on which humans use writing instruments to inscribe writings. The same materials can also be used for symbolic or representational drawings. Building material on which writings or drawings are produced are not included. The gross characterization of writing materials is by the material constituting the writing surface (for example, paper) and the number, size, and usage and storage configuration of multiple surfaces (for example, paper sheets) into a single object (for example, a spiral notebook). Writing materials are often paired with specific types of writing instruments. Other important attributes of a writing material are its reusability, its permanence, and its resistance to fraudulent misuse.
