Multi-ring binder features a sleek exterior design with durable and matte black covers and precision binder rings. Made from a unique and proprietary process, the polypropylene cover is rigid to protect the contents, yet lightweight for easy transport of your important presentations. PVC-free polypropylene is archival-safe and acid-free. A unique, center-mounted, multifold spine allows the binder to lie perfectly flat for presentations. Metal rings hold up to 40 sheets and are mounted on the back cover. Refillable binder includes exposed rivets and one pack of 10 sheets with crystal-clear clarity and glass-smooth texture.
