Business Source Heavy Duty Round Ring View Binder, 1/2" Capacity, White,

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. 1/2" capacity holds approximately 125 sheets. Binder also features two clear interior pockets and a sturdy chipboard core. Each pocket holds 40 sheets.
