Ring Binder Biurfol A4 4 cm spine, 2-ring, navy blue

Biurfol A4 ring binder with a 4 cm spine and a 2-ring mechanism in navy blue provides a compact storage solution for punched A4 documents and light inserts. The binder is sized for standard A4 paperwork and is intended to keep sheets aligned and protected while occupying minimal shelf space. Its straightforward construction supports office filing, personnel records and short-term archiving needs.

Advantages

The 4 cm spine allows storage of a modest volume of punched pages while keeping the binder slim and easy to handle. The 2-ring mechanism secures documents and enables simple addition or removal of sheets. The navy blue finish offers a neutral, professional appearance suitable for mixed office environments.

How to use
