Wire binding is one of the most popular binding styles:
1. Tamper-Resistant - twin loop wires require specialized equipment to unbind and rebind, which makes them tamper resistant.
2. Lays Flat - Wire-bound books lay flat when opened, and the pages can be turned to the back of the book (similar to a spiral-bound notebook) for ease of use when taking notes.
3. Sophisticated - Documents bound with duo-wire have a sophisticated and professional look that can't be matched by plastic coils or combs. Along with the tamper-resistant properties that they carry, the polished look of twin loop wire is one of the main reasons that wire binding is the most common style used in legal and financial industries.
4. Strong - Because they're made from metal instead of plastic, twin loop wires are extra strong, and documents bound with them can stand up to years of use.
