A comb binder is a device used to bind multiple sheets of paper together using a plastic comb. This comb has several rings that hold the pages securely, allowing them to lay flat when opened. Comb binding is popular for creating reports, presentations, and manuals because it is easy to use and provides a professional appearance. The process involves punching holes along the edge of the pages and then inserting the plastic comb through these holes. Comb binders come in various sizes, accommodating different numbers of pages, and are often used in offices, schools, and print shops for efficient document organization.
