Sheet lifters are included in all capacities to help keep pages properly lined up to prevent tears and damage. Heavy-duty recycled chipboard core is designed for heavy use. Binder also offers exposed rivets and two clear inside pockets. 5" capacity binder holds up to 1,050 sheets and includes locking ring, finger notch and hinged front cover.
