## Long description

The Donau 2‑ring A4 binder with a 40 mm spine in black is a durable filing solution designed to hold punched A4 documents securely on two rings. Its 40 mm capacity accommodates a substantial volume of papers while the standard ring spacing keeps pages aligned for smooth turning. The binder features a hard cover that protects contents from wear and helps keep documents flat for storage and transport.
Advantages
The binder offers robust construction suitable for frequent handling and long‑term archiving. Its 40 mm spine provides clear spine visibility on shelves while remaining compact enough for standard cupboards and filing cabinets. The two‑ring mechanism is simple to operate and ensures reliable document retention without excessive bulk. The black finish gives a neutral, professional appearance that fits office, school, or home environments.
Suitable for
Archiving reports, invoices and manuals in A4 format
Organizing single‑subject course materials or project documentation
Storage of punched sheets, worksheets and reference documents
Use in offices, schools, libraries and home filing systems
Key specifications
Format: A4 compatible
Ring type: 2 rings
Spine width: 40 mm capacity
Colour: black
Cover: rigid/hard cover for protection
Ring spacing: standard for punched A4 sheets
How to use
Open the two‑ring mechanism using the designated tabs or levers, align punched A4 sheets on the rings and close the mechanism until it locks. For best results, distribute pages evenly to avoid uneven strain on the rings and close the binder completely when storing or transporting. To remove pages, open the rings, slide out the sheets and close the rings again securely.
Usage recommendations
Store the binder upright on a shelf to maintain spine shape and avoid overfilling beyond the 40 mm capacity to preserve ring alignment. Use standard punched A4 paper with matching hole spacing to ensure smooth operation of the rings.
