A4 Ring Binder Biurfol SE-48-02, 55 mm spine, blue

A4 ring binder Biurfol SE-48-02 with a 55 mm spine in blue is designed to store and organize punched A4 documents. The binder offers a full-height cover and a sturdy ring mechanism that keeps loose sheets aligned and protected. Its 55 mm spine provides clear visibility on a shelf and room for several dozen to hundreds of sheets depending on paper thickness. The cover material is durable for regular handling in office, home, or school environments and the visible spine width helps fast retrieval and consistent filing.

Advantages

The binder combines a robust cover with a reliable metal ring mechanism to prevent page slipping and reduce wear. The 55 mm spine increases capacity while maintaining a compact footprint on shelves. A uniform blue exterior supports visual organization by color-coding files, and the visible spine width simplifies identification. Construction is intended for repeated opening and closing and for long-term document storage.

Key specifications

• Format compatibility: A4 punched documents
• Spine width: 55 mm for medium to high capacity
• Ring type: metal ring mechanism for secure closure
• Cover: durable rigid cover with full-height protection

How to use

Open the ring mechanism using the release tabs or levers, insert punched A4 sheets onto the rings and close until the mechanism locks to ensure pages are secured. Place documents in the binder so that page orientation and margins are consistent. Store the binder upright on a shelf using the visible spine width for quick identification. For large volumes, distribute sheets evenly to avoid overloading one side of the rings.

Usage recommendations

For long-term archiving, use acid-free punched sleeves or dividers to maintain document condition. Avoid forcing excessive sheets beyond the 55 mm capacity to prevent ring deformation. Keep the binder in a dry, cool environment to preserve the cover material and paper inside.
