A durable two-inch steel spine, precision Swedish engineering, and an ingenious dual-hinge mechanism highlight the Optimum Binder, the world’s most dependable binder. This steel-backed 3 ring binder is ideal for anyone who needs to continuously reference internal contents, made easier with the two settings of the dual-hinge ring mechanism. With one press of a finger, the rings part slightly, allowing the user to easily flip back and forth between pages. Press down again and the rings open completely to add or remove pages. Metal and heavy-duty cardboard combine to craft a durable, long-lasting binder surely to last for the next 100 years.
