The OEM Samsill Earth's Choice 189 Insertable View Binder is an eco-friendly option that features removable rings, making it 100 percent recyclable. Constructed with a sturdy chipboard core made from recycled materials, it is designed with acid-free, PVC-free polypropylene for environmental safety. A portion of the proceeds from each binder purchased is donated to American Forests to help plant a minimum of 7,500 trees annually. The binder includes clear overlays on the front, back, and spine for easy customization, and its locking metal round rings are mounted on the back cover to reduce wear and allow letter-size pages to lie flat. With a 4-inch capacity, it holds approximately 700 sheets and includes two clear inside pockets for storing additional loose papers.
