Binders feature a unique overlay design that makes it quick and easy to insert cover materials behind ink transfer resistant clear overlays when preparing presentation binders. Spine and front cover inserts slide in at the same time on a single sheet of paper. While uniquely shaped back-mounted Quick Load angle D-rings save you time loading paper and result in a double-hinged cover and narrower spine that takes up to 25 percent less shelf space than traditional round ring binders. Ring shape and rear mounting lets paper lie perfectly flat. Binders include antimicrobial protection against bacteria, fungus and mold. Commercial-grade heavy-duty construction is designed for frequent reference and longevity. Made with 100 percent recycled solid board that contains approximately 90 percent post-consumer material.
