Spiral binding is a method of securing pages together using a durable plastic or metal coil that spirals through holes punched along the edge of the document. This binding style allows the document to lie flat and even fold back on itself, making it convenient for note-taking and presentations. Spiral binding is commonly used for reports, manuals, notebooks, and project documents. It offers a professional appearance while being flexible and easy to use. The coils come in various colors and sizes to accommodate different page counts.
