Lakehead University custom binder covers and guest directory covers are another new and creative design from Impact that has excited the hospitality industry. In our continuing research to maximize 'green' for our environmentally responsible products, we have developed a new spine design for multiple inserts that maximizes green by minimizing the use of metal components for binding. These branding quality, elegant, and truly green binder covers are solid walnut with laser-engraved artwork that is color-filled. Available in all solid woods, including our new and unique treatment for plywood binder covers.
