Round-ring view binder offers crystal-clear, wrinkle-free, nonglare overlays that resist toner transfer & quality no-gap rings that close securely & resist separation. For durability & resilience, the cover material & overlays are made from polypropylene with a heavy board material in the front & back covers. Steel ringlets are attached to the inside back cover instead of the spine so pages lie flat. 2" capacity holds approximately 475 sheets. Binder also features two clear interior pockets, a sturdy chipboard core & exposed rivets. Each pocket holds 40 sheets.
