Quality from Start to Finish
The Staples nonstick 3-inch D-ring binder begins with a solid core of high-quality chipboard that's machine-sealed inside nonstick vinyl, making the notebook tough enough to withstand heavy use and gentle enough to preserve important documents. Three specially designed D-rings are firmly attached to the ring mechanism, which is back mounted to ensure pages lie flat. These solidly constructed loops give the Staples 600-sheet view binder a high-volume capacity that's usually associated with much larger note-books.

Extras
Designed for High-Use Environments In addition to internal pockets for quick storage, a Staples flexible spine D-ring binder has a one-touch button that opens and closes the rings, easing strain on fingers and hands. The reinforced, rubberized spine and edges offer extra protection where it's needed most.
