Locking Slant-D Ring Binder features no-pinch rings that open, close and lock with one touch. Holds 25 percent more sheets than standard round-ring binders. Made from polypropylene so contents will not stick to the binder cover. No more scratched desks or bookshelves from triggers that don't close. Received the Arthritis Foundation's "Ease-of-Use" Commendation. Safer and easier to use than any other ring metal. Binder has horizontal pockets inside front and back covers. Includes flat poly sheet lifter.
