How to use

Open the two-ring mechanism by operating the release tabs, insert punched A4 sheets or punched plastic sleeves, then close the rings until they click into place.

Store the binder upright on a shelf to prevent warping of the covers and avoid overfilling to maintain the mechanism's longevity.

Usage recommendations

For long-term archiving, use punched archival sleeves to protect important documents from wear and to reduce direct contact with the ring mechanism. Keep the binder in a dry, cool environment and avoid exposure to direct sunlight to preserve colour and material integrity.
