Multi-ring binder features a sleek exterior design with durable and matte black precision steel 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. A unique, center-mounted, multifold spine allows the binder to lie perfectly flat for presentations. Binder includes one pack plus bonus sheet with crystal-clear clarity and glass-smooth texture. Binder is refillable. Design is archival-safe and acid-free.
