The Change About multi-purpose ring binder is equipped with an easily controllable opening and closing mechanism. This simple turning mechanism allows easy handling and prevents fingers from getting caught in it. The special key, which is attached to it with a ribbon, for this purpose simply needs to be inserted into the slot at the ring binding bar and turned. The rings will then open or close smoothly and securely. A snapping shut suddenly is thereby prevented. The ring binder is available in various colours, a subtle leather pattern exudes a high-quality appearance.
