Made with heavy-duty hardboard covers, metal piano hinges, and a metal-reinforced spine, this rugged 3-ring binder is ideal for long-term archival storage. The unique elliptical-shaped rings hold more paper than the common round three-ring mechanisms. The spine pocket with a removable spine label makes it easy to classify binder contents. Favored by libraries, law offices, research institutes, and historical societies, this durable binder is perfect for preserving and safekeeping frequently referenced documents.
