Ring Binder Biurfol SE-49-01 A4 4-ring 65 mm spine black

The Biurfol SE-49-01 A4 4-ring binder with a 65 mm spine in black is designed for storing and organising punched A4 documents. Its four metal rings provide secure fastening of documents while the wide spine increases capacity for larger sets of papers and inserts. The binder has a simple, professional appearance suitable for office, home or school environments and for tasks such as filing, archiving and document transport.

Advantages

The binder combines a durable cover and four metal rings to ensure reliable document retention and long-term use. The 65 mm spine offers increased storage capacity compared with slim binders, allowing multiple reports, manuals or thick project files to be kept together. The neutral black finish provides a professional look and reduces visible wear, while the ring mechanism allows easy opening and closing for frequent updates.

How to use

Open the ring mechanism and align punched document holes with the rings before closing to secure pages. For best balance and ease of turning, distribute pages evenly and avoid overfilling beyond the 65 mm capacity. Use dividers or index tabs to separate sections and insert title sheets into the front pocket or onto the cover if available. When transporting, keep the binder upright to minimise shifting of contents.

Usage recommendations

For durable storage, avoid placing heavy objects on top of the binder and store in a dry environment to prevent warping. Periodically check the ring mechanism and realign rings if pages do not turn smoothly. Use PVC-free sleeves for document protection where long-term preservation is required.
