The Avery Economy 1 inch binder is a basic binder that exceeds expectation. Unlike other basic binders, this Economy binder is fully adhered with a deep-weave polypropylene cover that is resistant to bubbling and surface wrinkles. It also has a textured pattern that is tear-resistant. The interior of this binder is just as impressive as its exterior. With back-mounted 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. Enjoy extra organization and storage capabilities with two interior clear pockets made of nonstick material that won't lift or transfer ink from your documents. This classic red Economy binder is perfect for light usage like filing important documents or building a presentation book. Each binder holds up to 175 sheets of paper with 1 inch capacity rings. Rings are standard 3-hole spaced and accommodate 8.5" x 11" pages nicely. All Economy binders are made with PVC-free material.
