How to use
Open the metal rings using the mechanism provided, insert punched A4 sheets onto the rings and close until the rings are fully engaged. Arrange documents in the desired order before closing to ensure correct pagination. Store the binder upright on a shelf or in a filing cabinet compatible with A4 binders. For removal of individual pages, open the rings, reposition or remove sheets as needed, then close the rings securely to prevent slipping.
