Quite an under-utilised form of binding. It looks similar to wire binding, except that it is solid plastic. It can be re-used like plastic ring binding, meaning that you can replace pages without destroying the binding, but it does not even remotely look like plastic ring binding. Applications would be similar to the applications for wire and plastic ring binding and it is quite a nice looking binding that is different from the one that the Jones's are using!
