## Summary description

Lever-arch ring binder Donau in A4 format with a 50 mm spine, suitable for filing and organising documents. Features a metal lever-arch mechanism for secure binding and easy opening, a durable cover in pink, and capacity for large document sets.

## Long description

Donau lever-arch ring binder in A4 format with a 50 mm spine provides a practical solution for filing and organising punched documents. The binder includes a metal lever-arch mechanism that secures papers reliably and opens smoothly for adding or removing sheets. The durable pink cover protects contents from wear and helps visually differentiate folders in a filing system, offering capacity for thick documents such as reports, manuals and project files.
Advantages
The strong metal lever-arch mechanism enables quick and secure fastening of punched sheets and ensures even pressure across the stack. A 50 mm spine increases storage capacity without significantly increasing shelf depth. The rigid cover resists bending and protects documents from dust and damage, while the bright pink colour improves visibility and organisation. The binder is suitable for repeated use and maintains alignment of documents during handling and transport.
Suitable for
Office filing of reports, invoices and client records
School and university coursework, project documentation and lecture notes
Home administration such as manuals, warranty papers and bills
Project and archive storage where clear visual identification is needed
Key specifications
Format: A4 (suitable for standard A4 punched paper)
Spine width: 50 mm for medium to large document stacks
Closure mechanism: metal lever-arch for secure and easy operation
Cover material: durable rigid board for protection against bending
Colour: pink for easy visual identification
How to use
Open the metal lever to release the rings, align your punched A4 pages on the rings and close the lever to secure the documents. To add or remove sheets, lift the lever to open the rings, reposition pages as needed and then close the lever again. Store the binder upright on a shelf or flat in a drawer; keep it away from prolonged direct sunlight and high humidity to preserve the cover and internal mechanism.
Usage recommendations
For best results, use correctly punched A4 paper and avoid overfilling beyond the 50 mm capacity. Distribute heavy content across multiple binders when storing large volumes to reduce stress on the mechanism and covers.
