The Case-it Dual 2.0 Zipper Binder has two separate sets of rings, for a total storage space equivalent to a 4-inch binder. This binder can hold up to 800 sheets of paper! Each set of rings is seperated for easy organization and reference. The “hold down pages” keep all of your papers secure to their side like paper weights. 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. Easily take your school work home with you because every Dual 2.0 comes with a “hold down page” that doubles as a removable 5 Subject expanding file folder. Its shoulder strap or handle make the binder easy to carry from school to home or class to class.
