Every in-office binding project needs the perfect binding supplies to make it complete. CFS 12-mm (1/2-inch) Binding Combs allow you to create professional-looking bound projects affordably and easily. Spiral comb binding offers documents both a professional, finished look and a lay-flat design with the ability to flip pages 310° from front to back. These plastic combs are an excellent high-quality choice for business proposals, directories, staff handbooks, annual reports, company presentations, restaurant menus, and more! Plastic spiral combs from CFS are made of high-quality plastic that wont bend or snag. Each comb is pre-cut to 11 inches long, making them the perfect choice for binding spines for standard letter-sized documents.
