Round-ring binder features a material that will not stick to cover inserts or materials stored inside. Material is archival-safe for all documents including photos and offers superior, cold-crack resistance to 5 degrees Fahrenheit. Clear, nonglare overlays on the front, spine and back hold your customized title sheets. Use free online templates to customize. Back-mounted, steel rings with dual opening and closing triggers allow sheets to lie flat. 1-1/2" ring capacity accommodates approximately 350 sheets of letter-size documents. Horizontal pockets on the inside front and back covers secure loose, unpunched documents. Each pocket holds 40 sheets. Binder also features exposed rivets and a sturdy chipboard core. Binder is made with a high percentage of recycled post-consumer content.
