A New Binding Style —— Proclick

ProClick Spines

There are few different sizes, ranging from 10mm to 22mm, and two kinds of pitch,9.5mm&3:1. With a larger size, you can fit up to 180 pages into your book.  

A nice thing about this binding is that it lays flat. Not only that but it even lays back to back. 

The best part is that you can add or delete paper. The zipper tool can be necessary to edit and open the spine.

To close it, pinch the end of the tool and swipe. To open it, slide the other end through. 

They have the 3:1 pitch punch patter, which means there are 34 holes exactly like the 3:1 twin loop wire. You can even use the same punching machine.
