Wire Binding
Also called spiral binding, the standard Wire-O binding is a type of binding comprising a set of loops inserted into punched or drilled holes along the binding edge of the book or set of forms. This binding method is known by various names, twin loop wire, double loop wire double-o ring wire and wire binding. Printed projects bounded in this method will open completely flat and allow 360 degree rotation on bound edge. This style of binding is perfect for cookbooks, notebooks, ticket books, instruction manuals, textbooks and calendars.
