Quill Brand® D-Ring Binders with Label Holder

The difference is in the construction! Round rings are mounted on the spine, making repeated opening and closing a burden on the binder and its contents The curved shape of the D-ring, and the fact that rings are mounted on the back cover rather than the spine, means there's less wear and tear on your pages Acid-free poly material will not stick to materials stored inside Environmentally friendly: does not contain PVC which produces chlorine gas when incinerated Archival safe for all documents including photos Superior cold-crack resistance, down to 0° Fahrenheit Front and back inside pockets for loose sheets Includes label holder
