Round-ring view binder offers crystal-clear, wrinkle-free, nonglare overlays that resist toner transfer and quality no-gap rings that close securely and resist separation. For durability and resilience, the cover material and overlays are made from polypropylene with a heavy board material in the front and back covers. Steel ringlets are attached to the inside back cover instead of the spine so pages lie flat. 1" capacity holds approximately 225 sheets. Binder also features two clear interior pockets, a sturdy chipboard core and exposed rivets. Each pocket holds 40 sheets.Round-ring view binder offers crystal-clear, wrinkle-free, nonglare overlays that resist toner transfer and quality no-gap rings that close securely and resist separation.
