The Avery Economy 1-1/2 inch binder is a budget binder that exceeds expectations. Unlike other basic binders, this blue 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. Economy binders are great for light-use activities like filing important documents or building a presentation book. You can also use them as school binders, photo albums, planners, recipe binders, and more. This set includes 3 blue binders. Each binder holds up to 275 sheets of paper with 1-1/2 inch capacity round rings and has a spine that is 2.1 inches wide. Rings are standard 3-hole spaced and accommodate 8.5" x 11" pages nicely. All Economy binders are made with PVC-free material.
