Worried about papers falling out of sheet protectors while in the ring binder? Side loading sheet protectors are sealed on three sides and loaded from the ring binding edge to secure the pages inside the holder. This assures that the contents will never fall out, even if the binder is turned upside down. Plus, the opening on the long side makes loading papers quick and easy. Heavy-gauge polypropylene construction for durability. No sheet punching necessary, keeping 8 1/2" x 11" size documents in original condition. Ideal for presentation use.
