Wire-O binding is a method of bookbinding that uses a double loop of wire to hold pages together. This technique allows the book to lay flat when open, making it ideal for notebooks, planners, and presentations. The wire is inserted through holes punched along the edge of the pages, providing a sturdy and flexible binding. One of the advantages of Wire-O binding is its durability. The wire can withstand frequent use without breaking, and it comes in various colors and sizes to suit different styles. This binding method is popular for both professional and personal projects, offering a clean and polished look.
