Round-ring binder with exposed rivets features a special ribbed seal to add flexible strength at the hinge for lasting stability. Premium-quality vinyl is tightly sealed over a rigid board to prevent your papers from folding or creasing. Clear overlay on the front, back and spine lets you easily customize the exterior for a unique, personalized style. Rust-resistant metal rings with double boosters keep all of your papers securely organized. Pockets inside the front and back covers provide a convenient location to hold loose materials. Round-ring binder is perfect for organizing presentations, manuals, projects and more.
