Spiral-O Supplies

Spiral-O is the only wire binding that conforms to the standard hole punching pattern of plastic binding machines. This binding is basically the same as above, but it allows you to punch your sheets 19 loop on your plastic binding machine and then bind by closing the wire on the E-Z closer.

Pages turn 360 degrees back to back, open and lay flat.

Colours available are black, white, blue, red and silver.

Diameters available are: 1/4", 5/16", 3/8" 7/16", 1/2", 9/16", 5/8", 3/4", 7/8" and 1".
