Wire-O Binding is a popular method of binding documents that uses a double loop wire to hold pages together. This technique allows the pages to lay flat when opened, making it ideal for presentations, reports, and manuals. The wire comes in various sizes and colors, providing options for customization. The process involves punching holes along the edge of the pages and threading the wire through these holes. Once the wire is secured, the ends are crimped to keep everything in place. Wire-O Binding is durable and offers a professional appearance, making it a favored choice for both personal and business projects.
