Basic view binder features a D-Ring mechanism that holds up to 25 percent more than conventional round rings. The locking metal rings are mounted on the back cover, leaving the spine clean and giving you the ability to fold the cover back and under. Store unpunched sheets in the two interior pockets. PVC-free, one-piece nonglare overlay on front, spine and back resists toner transfer for a clean impression every time. Heavy-duty construction is designed for tough wear and tear. Binder also offers exposed rivets and a sturdy chipboard core.
