Durable binder makes organizing your projects or reports quick and easy. EZD rings hold more paper than same-size round rings, and pages turn smoothly across rings. Back-mounted metal rings help pages lie flat. Two boosters on the rings allow even open and closing. You can also organize and secure loose and unpunched pages in the four interior pockets. Each pocket holds up to 20 sheets. Durable construction is ideal for frequent reference. Binder also features exposed rivets on the back and a sturdy chipboard core.
