Designed with toughness and durability in mind, the Avery Durable View binder stands strong where many basic binders fall apart. Its sturdy exterior features a tear-resistant spine (DuraHinge) and more flexible, split-resistant edges (DuraEdge). Durable binders are also fully adhered with a deep-weave polypropylene cover that is resistant to bubbling, surface wrinkles, and is tear-resistant.
