## Long description

Lever-arch ring binder Donau Master for A4 documents with a 75 mm spine in copper colour is designed to store and organise punched papers and documents efficiently. The binder uses a lever mechanism that enables secure closing and quick, smooth opening of the rings. Its high-capacity spine accommodates large stacks of documents while keeping them aligned and protected, making the product suitable for regular filing, archival storage and environments that require frequent access to paperwork.
Advantages
The lever mechanism provides reliable, one-handed operation for opening and closing the rings and ensures that documents are held firmly without slippage. A 75 mm spine offers high capacity while maintaining a compact profile on shelving. Durable cover materials resist everyday wear and the reinforced ring assembly improves longevity under frequent use. The copper colour gives a professional, neutral appearance suitable for office and institutional settings.

How to use
Open the binder by operating the lever to release the rings, insert punched papers onto the rings and close them using the lever until the rings are fully engaged.

Store the binder upright on a shelf or flat in a drawer; when moving or transporting, ensure the rings are fully closed to prevent pages from catching or falling out.
