The Small Card Organizer, or simply "Organizer", is an accessory that fits into a notebook binder and enables users to organize and transport card materials, especially educational flashcards. The Organizer is typically composed of a substrate (such as a three-ring binder insert sheet) to which is mounted a number of miniature-sized pouches called carriers. The carriers, enclosed on the bottom, front, side and back, provide a single opening through their top for inserting flashcards, but also for business cards, index cards, and photographs. To keep card materials from falling out through the carriers' openings, retaining members are also provided with the Organizer. Retaining members, most commonly resembling flaps, are fixed in place to the substrate or carriers.
