Gray Spiral Binding Coil 
They say an elephant never forgets. I certainly believe that's true, especially concerning our gray spiral coil. With its superior construction and durability, there's no way anyone could forget an encounter with our gray color coil. Likened to a donkey's fur, a gloomy rain cloud, or the skin of a rhinoceros (or elephant!), this traditional gray coil works well with all our coil binding machines and binding covers. If you're fed up with working for peanuts, use our gray spiral binding coil to make a huge impression.
