Heavy-duty binder features an EZ-Turn Ring designed for smooth page turning. Gap-Free ring feature prevents gapping and misalignment of rings. Nonstick, archival-safe material won't lift ink or toner off printed pages. Wide front and back binder panels fully cover standard dividers and sheet protectors. Organize and secure paper with two interior pockets. Pages lie flat with back-mounted rings. Overlay material is made of crystal-clear PVC-free poly. Back has exposed rivets.
