The OEM Business Source Slanted D-Ring Binder BSN33120 is designed for maximum sheet capacity. This binder features rings mounted on the back cover for lay-flat visibility and long-lasting durability. The no-gap D-Rings stay tightly closed without gaps and can hold 25 to 40 percent more paper than the same-size round rings, accommodating up to 835 sheets with a 4" capacity. Additionally, the nonglare CleanView cover and pocket material resist toner transfer, ensuring that ink from printed papers won't stick or mark the binder over time. This binder also includes exposed rivets, two clear interior pockets for extra document storage, and a label holder on the spine for easy identification.
