The Avery Heavy-Duty Vinyl EZD Ring Reference Binder is a revolutionary binder that lets you open, close, and lock it in one easy step. The Gap Free feature prevents ring misalignment, ensuring that pages turn smoothly. The locking EZD ring has up to 50% more capacity than the same size round ring. The back-mounted rings allow pages to lie flat, while the four clear inside pockets store unbound materials for improved organization. The wide front and back panels fully cover standard dividers and sheet protectors, and the exposed rivets on the spine add a touch of style. The nonstick, heavy-duty poly won't lift ink or toner off print pages, and it's PVC-free. Specifications Maximum Capacity Range ("): 1 in. Sheet Capacity: 275. Color(s): Blue.
