The OEM Samsill Insertable Vue Binder SAM18957 is an eco-friendly view binder designed for sustainability. It features removable rings, making the binder 100 percent recyclable, and a sturdy chipboard core made from recycled material. The acid-free, PVC-free polypropylene ensures that the binder is environmentally safe. Clear overlays on the front, back, and spine allow for easy customization, while the locking metal round rings mounted on the back cover reduce wear and help letter-size pages lie flat. With a 1-1/2 inch capacity, it holds approximately 350 sheets and includes two clear inside pockets for additional loose papers.
