Key specifications
 Format: A4
 Ring type: 4-ring metal mechanism
 Spine width: 20 mm
 Color: navy blue
 Compatible with standard punched A4 paper and refill sheets
 Cover: durable, stiff material for everyday use
How to use
Open the 4-ring mechanism and align punched A4 pages with the rings before closing them securely. For best results, insert pages that match standard A4 hole spacing and avoid overfilling beyond the 20 mm spine capacity. Store the binder upright on a shelf or lay flat for transport; when carrying, ensure the binder is closed to prevent pages from slipping out.
Usage recommendations
To extend the life of the binder and maintain neat organization, distribute contents evenly, avoid forcing additional sheets past the spine capacity, and use protective sleeves for frequently handled documents. Regularly check the ring mechanism for proper alignment to prevent paper snags.
