Twin Loop Wire binding is a popular binding style available for individuals who want a professional and durable bind. Twin loop wire binding comes out of the package in a C shape and a wire binding machine is used to close the wire binding so that it is round. Twin loop wire binding provides an elegant look and feel but is slightly more expensive than coil binding or wire binding. Depending on the use, this is often worth the extra cost. Twin loop wire binding has all of the advantages of coil binding above. Pros – slick and sturdy look. Cons – don’t lay heavy loads on top of your presentations, you might bend the wire which makes the pages harder to turn.
