Keep your workspace organised and clutter-free with the Winc Earth™ A4 insert binder. With a 4-D ring mechanism and a 38mm diameter capacity that can hold up to 250 sheets of A4 80gsm paper, your workspace will be catalogued and efficient afterwards. Constructed from a heavy-duty board for extra strength and durability, and boasts a polypropylene cover that is glued to the board instead of welded - which removes the trapped air and eliminates the chance of crinkling. Each binder features a clear insert pocket on the front, back and spine that is ideal for presentations and conferences. Includes inside cover pockets.
