One Touch ™ rings are perfect for extended use. From reference manuals, daily classroom notes to your home office - this is engineered to take on any task. The DuraHinge design is stronger, lasts longer and resists tearing, while the DuraEdge feature makes the sides and top more pliable to resist splitting. Our deep texture film offers a smoother finish and features a linen pattern for a high-quality look and feel. Just pull the lever to open the rings for adding, replacing and removing pages. Then push to lock the rings in place. Even when filled to its 540-page capacity, it still has four stacked pockets for a bit of extra space inside.
