Since MyBinding is located in Oregon, arguably the "greenest" state in the Union, we're thrilled to support environmentally-friendly initiatives like Envirokoil. Made from more than 90% post-commercial waste, Envirokoil green spiral coil is the must-have binding coil for our eco-conscious customers. Appropriately imitating a dark forest green, this spiral coil functions like any other spiral coil we carry--with quality and strength. Fully compatible with most of our coil binding machines as well as our paper and plastic binding covers, you won't help but feel great about the look of your presentation, not to mention what you're doing for the environment, too.
