Eco-friendly view binder features removable rings that make the binder 100 percent recyclable. Sturdy chipboard core is made from recycled material, and the acid-free polypropylene is environmentally safe. A portion of the proceeds from each binder purchased is donated to American Forests to help plant a minimum of 7,500 trees annually. Clear overlays on front, back, and spine allow easy customization. Locking metal round rings are mounted on the back cover to reduce wear and let letter-size pages lie flat. 1/2" capacity holds approximately 125 sheets. Two, clear inside pockets store additional loose papers. Design also includes exposed rivets.
