How to use

Place punched A4 sheets onto the ring mechanism by opening the rings, aligning the paper holes with the rings and closing them until they click securely. Use the spine area or cover to attach a label for easy identification when stored on shelves. For archival storage, distribute contents evenly across the binder to prevent uneven pressure on the spine and to maintain the shape of the cover over time.

Usage recommendations

For prolonged durability, avoid overfilling beyond the 80 mm spine capacity and store the binder upright on a shelf. Use reinforced punched pockets for loose or frequently handled documents and apply adhesive labels on the spine for quick retrieval.
