Designed to last, Avery 79886 Heavy-Duty Blue 5 Inch Binders are perfect for long-term storage and everyday use. Created with durable, non-stick polypropylene, Avery Heavy-Duty Binders are built to defend your documents from everyday wear and tear. Our DuraHinge technology helps avoid tearing along the spine and our DuraEdge technology makes the sides more pliable to resist splitting. The wide front and back panels are great for protecting sheet protectors and divider tabs. The 5 inch rings use our EZD design that opens with ease and can keep up to 1,050 pages secure. EZD rings can also hold up to 50% more sheets than round rings of the same size. The binder rings are mounted on the back cover to keep your pages flat to avoid creasing and for easy flipping. Four interior pockets are included to store loose sheets and extra documents. Whether you need binders for school, a presentation binder or a trading card binder, organize your next project with Heavy-Duty Avery Binders.
