"Wire-bound" refers to a method of binding pages together using a metal wire. This technique is commonly used in notebooks, planners, and other types of bound documents. The wire creates a sturdy spine that allows the pages to lay flat when opened, making it easier to write or read. This binding method is popular for its durability and flexibility. Unlike traditional glue or plastic bindings, wire-bound books can be opened 360 degrees, which is especially useful for artists and students who need to work on both sides of the page. Overall, wire-bound products offer a practical solution for organizing and presenting information.
