Spiral Coils are a type of binding used to secure loose sheets of paper or other materials together. The coil is typically spun or twisted through the holes using a special machine, creating a durable and flexible binding. They consist of a continuous plastic or metal coil that is threaded through a series of evenly spaced holes along the edge of the document. These coils are commonly used for reports, presentations, manuals, calendars, notebooks, and other types of documents where durability, flexibility, and ease of use are essential. Spiral Coils are available in various colors and sizes, allowing for customization to match the document's aesthetic or functional requirements.
