The Case-it Dual Zipper Binder has two separate sets of rings, for a total storage space equivalent to a 3-inch binder. Use up to 600 sheets in all. Each set of rings is seperated for easy organization and reference. The convenient “hold down pages” keep all of your papers secure to their side like paper weights AND they even provide extra storage for your writing tools! This practical zipper binder closes completely to protect the contents from falling out or getting damaged. An additional pencil pouch comes included to store pens, pencils, and other essentials. Easily take your school work home with you because every Dual Binder comes with a shoulder strap and handle.
