## Summary description

## Long description

Donau Premium lever ring binder in A4 format with a 50 mm spine capacity in purple is designed for organised storage and quick retrieval of loose-leaf papers. The binder uses a lever mechanism to open and close the rings, allowing fast insertion and removal of documents. Its A4 size accommodates standard office sheets, reports and manuals while the 50 mm spine provides space for a large stack of punched pages.
Advantages
The lever mechanism ensures controlled opening and closing of the rings, reducing the risk of misalignment and damaged paper edges. The 50 mm spine capacity allows storage of thick reports or multiple document sets in one binder. Durable cover material and a reinforced spine provide stable support for stacked documents and frequent handling. The purple finish makes it easy to colour-code files for quick identification.
Suitable for
 Office filing of reports, contracts and project documentation
 School and university notes, assignments and course materials
 Home organisation of manuals, receipts and personal records
 Archiving multiple punched documents and loose-leaf collections
Key specifications
 Format: A4
 Spine capacity: 50 mm
 Ring type: lever-operated circular rings
 Colour: purple
 Cover: rigid, reinforced for document protection
How to use
Open the binder by operating the lever to release the rings, place punched pages onto the rings and then close the rings using the lever until they align and secure the documents. For best results, align hole-punched sheets before placing them on the rings and avoid overfilling beyond the 50 mm capacity to maintain ring alignment and ease of use. Store the binder on a shelf upright or stacked flat, ensuring even weight distribution to prevent bending.
Usage recommendations
Use reinforced punched holes or plastic reinforcements for frequently handled pages, and separate large volumes into multiple binders if the content approaches full capacity to preserve ring function and document condition.
