D-Ring binder features an all-natural, silver-based antimicrobial additive by Agion that prevents the growth of bacteria, mold and mildew on the binder surface. Ideal for promoting cleaner offices, schools, and hospitals. Organize your binder with fast-reference label holders. Locking D-ring holds 25 percent more sheets than a standard round ring. With heavy-duty construction, binders are built to last. Two clear, inside pockets provide extra storage for loose documents. Rings mounted on the back lid allow pages to lie flat and reduce wear. Binder holds letter-size documents.
