Ring Binder Donau 2-ring A4 35 mm blue — Donau 3732001PL-10

Donau 2-ring A4 binder with a 35 mm spine in blue is designed to store and organise punched A4 documents reliably. The binder has two metal rings that secure papers with standard 2-hole punching and a 35 mm capacity that accommodates a moderate stack of sheets. Its durable cover protects contents during daily handling in office, home and school environments, and the slim profile keeps files neat on shelves or in cabinets.

Advantages

The binder offers a balance of capacity and compactness, making it suitable for ongoing projects and regular filing. Metal two-ring mechanism provides stable fastening and reduces page shifting. The cover material resists everyday wear and helps protect documents from dust and light damage. Its standard A4 format and two-ring system ensure compatibility with commonly punched paper and most filing systems.

Suitable for

• Organising reports, meeting notes and project documentation
• Storing study materials and school assignments
• Keeping manuals, brochures and reference sheets
• Archiving invoices, contracts and administrative records

How to use

Open the ring mechanism and insert punched A4 sheets aligned with the two rings. Close the rings until they click to ensure the pages are secured. Arrange documents in logical order and use dividers or tabs if needed to separate sections. Store the binder vertically on a shelf or horizontally in drawers to maintain the spine shape and protect contents from bending or creasing.

Usage recommendations

For best results, use standard two-hole punched A4 paper and avoid overfilling beyond the 35 mm spine capacity. Periodically check and realign pages to prevent strain on the ring mechanism; store the binder in a dry indoor environment to preserve the cover and documents.
