Abstract
A method for manufacturing improved paper office supplies comprises determining which critical areas or portions of the office supplies are prone to wear and tear, and applying reinforcement upon or adjacent to those critical areas or portions to increase the strength and resistance of the office supplies to such wear and tear. This invention also provides some examples of reinforced paper office supplies.
