Wire-O binding wires from Lamination Depot are fully compatible with all standard wire binding machines, including models from Akiles, USI, GBC, Ibico, NSC, Tamerica, Fellowes, and HIC. These heavy-duty, metal binding spines are available in a wide range of colors and sizes, and are perfect for reports, presentations and any other book binding projects.
