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 capacity holds approximately 225 sheets. Two clear inside pockets store additional loose papers. Design also includes exposed rivets.
