Plastic Binding Coil, 16mm, Silver, 100/box

4:1 Pitch Plastic Coil is a durable, flexible, and an affordable alternative to other binding methods. Available in a variety of colors and sizes to finish almost any job. It will not chip, crack, corrode or distort over time, and will retain its shape even with repeated use. Plastic coil bound document pages will open a full 360°; (front-to-back) and lie perfectly flat. The multiple hole format makes the binding extra strong and the plastic coil's "memory" resists bending and with its lightweight construction it's great for mailing.
