The Case-it Classic Zipper Binder is an efficiently designed 3-ring binder with 2-inch O-rings, rigid body construction and a handle and shoulder strap. This convenient binder also features a full mesh pocket on the outside and two inner pockets for easy organization. The Classic Binder uses Kraft board instead of PE board to give its binders a firm, stiff shape that won't buckle or warp. The spine is specially designed so that your binder can lay flat when open, making it easier to add or take papers out, and to take notes in. Case-it produces quality binders offering unique organizational tools for school or home use.
