How to use
Open the lever-operated mechanism to release the rings and insert punched A4 sheets evenly along the rings. Close the lever to lock the rings securely and ensure sheets are aligned to avoid bending. Use the spine to label the binder for quick identification; store the binder upright on a shelf or flat in a cabinet depending on space and access needs. When adding or removing large groups of pages, open the lever fully to minimize stress on the mechanism and pages.
Usage recommendations
For best results, use standard punched A4 paper and avoid overfilling beyond the 50 mm capacity. Label the spine clearly and store the binder in a dry environment to maintain cover condition. Periodically check the lever mechanism for smooth operation and realign pages before closing to extend the product’s service life.
