If you're looking for a binder that is stronger, lasts longer, and can hang tough with even the most demanding activities, look no further than this 2 pack of Avery Heavy Duty 4 inch binders in black. The sturdy exterior features a tear-resistant spine (DuraHinge) and more flexible, split-resistant edges (DuraEdge). Heavy Duty binders are also fully adhered with a deep-weave polypropylene cover that is resistant to bubbling, surface wrinkles, and is tear-resistant. The interior of this binder is just as impressive as its exterior. With back-mounted slant rings, your pages will never curl again. Pages lay flat and are easy to turn, while the cover opens and closes without pulling on your papers. The One Touch slant rings lock securely but release at the touch of a button.
