Turn any report or presentation into an impressive, bound work with these professional, 19 ring, wire binding spines! These wire rings are compatible with the holes punched by any plastic comb binding machine. Once holes have been punched into the paper, simply insert the wire into their proper placements and close using a wire closer machine.

Please note that Spiral-O Wire is not a continuous spiral and has no pitch options (e.g. 2:1 or 3:1). This is a 19 ring wire binding. Please ensure you are not looking for Double/Twin Loop Wire (found here), which is a continuous 21- or 32-ring spiral and comes in a 2:1 or 3:1 pitch.

This style of binding is more commonly purchased in the plastic version, the 19 Ring Comb Bindings, which is also available in a wider array of colors and sizes.
