How to use
Open the rings, align punched sheets with the ring openings and close the rings until they lock to secure pages. Place labelled dividers or sheet protectors on the rings if needed for organization or document protection. Store the binder upright on a shelf or flat in a drawer to keep contents flat and accessible. For frequent additions or removals, open the rings gently to avoid bending or misaligning the metal rings.
