For convenient organization of your documents, it doesn't get much simpler than this handy Economy Binder. Metal round rings mounted on the spine hold your letter-size papers securely in place to let you flip through notes, reports and more without getting your pages out of order. Binder is ideal for your class notes, employee handbooks and other important papers. 1/2" ring capacity holds up to approximately 100 sheets. Slip loose pages into the two interior pockets for easy access later. Each pocket holds up to 20 sheets. The black matte cover and spine combine with a black matte interior to reduce glare.
