Slant-D ring binder offers superior, professional presentation for a volume of paperwork. Design features thick vinyl and double-polished, wrinkle-free, nonglare overlays that resist toner transfer. For durability and resilience, the cover material and overlays on front, spine and back are made of polypropylene. Quality no-gap rings close securely and resist separation. Steel ringlets are attached to the inside back cover instead of the spine so pages lie flat. 1" ring capacity holds approximately 240 sheets. Binder design provides increased capacity in the same shelf space over similar-sized, round-ring binders. Binder also features exposed rivets, a sturdy chipboard core and two clear interior pockets. Each pocket holds 40 sheets.
