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. 1-1/2" ring capacity holds approximately 375 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.
