With spiral binding plastic coils, you can make professional books that can withstand heavy handling. This is because the plastic itself is incredibly flexible and durable, with the ability to be bent any which way and still retain its original shape.
Binding with coil is simple and only requires a few tools. You will need a coil binding punch, the coils themselves, and cutter crimper pliers. An optional addition would be an electric coil inserter to increase the rolling/inserting speed. All you have to do is punch your pages, roll your coils through the holes, and then cut/crimp in each end of the coil.
