The OEM Cardinal EasyOpen 11" x 17" Tabloid Binder features innovative no-pinch rings that open and close easily, providing quick access to your tabloid-size documents. This binder locks with just one touch and holds 25 percent more than standard round-ring binders, accommodating approximately 350 sheets with its 1-1/2 inch ring capacity. The back-mounted steel rings reduce wear and allow pages to lie flat, ensuring durability. Constructed with a heavy-gauge vinyl cover and a sturdy chipboard core, this binder protects your contents while being made with a high percentage of recycled material.
