Wire-bound books are a type of binding that uses a metal wire to hold the pages together. This method allows the book to lay flat when opened, making it ideal for notebooks, sketchbooks, and planners. The wire binding is often seen in products like spiral notebooks and coil-bound journals, providing durability and flexibility. The wire binding process involves punching holes along the edge of the pages and threading a wire through them. This technique is popular for its ease of use and the ability to add or remove pages. Wire-bound books are commonly used in both educational and professional settings.
