Slant-D ring binder is designed for maximum sheet capacity. Rings are mounted on the back cover for lay-flat visibility and long-lasting durability. No-gap D-Rings stay tightly closed without gaps and hold 25 percent more paper than the same-size round rings. 1" capacity holds up to 240 sheets. Nonglare CleanView cover and pocket material resist toner transfer so ink from printed papers won't stick or mark binder, leaving a clean impression over time. Three-ring binder also offers exposed rivets and two clear interior pockets for additional document storage and double opening/closing boosters. Label holder on spine allows easy identification. Binder is made of polypropylene covering sturdy chipboard for durability.
