Key specifications
Format: A4
Spine width: 80 mm
Colour: black
Ring mechanism: three-ring style for secure page retention
Cover: reinforced for document protection
How to use
Open the ring mechanism and place punched sheets evenly on the rings, ensuring holes align with the ring positions. Close the rings until they click to secure pages in place. For thicker stacks, distribute pages across multiple binders to avoid overstressing the mechanism. Store the binder upright on shelves or flat in archives to maintain shape and protect contents from dust and moisture.
Usage recommendations
Use archival-quality punched sleeves for frequently handled or valuable documents to reduce wear. Label the spine clearly for fast retrieval and consider dividing large collections with index tabs or separators to improve organisation.
