Bundle swatches of fabric and card with these loose leaf rings. The 3-inch diameter means they can hold around 570 sheets of paper, so this pack of 10 rings provides ample supplies for multiple workstations. The hinged closure lets the rings open and close easily when you want to remove or add items, and the pull-push split opposite the hinge makes them secure. These silver-colored Staples loose leaf rings are made of nickel-plated steel for strength and rust resistance.
