Ring type: 4 metal rings

How to use
Open the ring mechanism and insert punched A4 sheets onto the metal rings, ensuring the punched holes align with the rings. Close the rings securely so pages lie flat and turn smoothly. Place the binder upright on a shelf or store it horizontally, using the spine for quick identification. For bulk filing, distribute inserts evenly to avoid overstressing the rings.
Usage recommendations
To preserve the binder and contents, avoid overfilling beyond the spine capacity, keep the cover clean and dry, and open the rings gently to prevent misalignment. Use reinforced punched sheets or plastic sleeves for frequently handled documents to extend their longevity.
