With this Heavy-Duty Binder you get one-touch operation and everyday durability. The DuraHinge design is stronger, lasts longer and resists tearing, while the DuraEdge feature makes the sides and top more pliable to resist splitting. A deep texture film offers a smoother finish and features a linen pattern for high-quality look and feel. The exclusive EZD rings open and lock closed with one touch, and hold more sheets than the same size slant and round rings. Also, the rings' gap-free design keeps your papers secure so they won't fall out. Even when filled to its 540-page capacity, this binder has four stacked pockets for extra space inside the covers. The binder is made with a nonstick poly construction for maximum performance, and features wider front and back panels cover standard size dividers and sheet protectors.
