Ring binder Donau Life A4 2-ring 30 mm green (DONA0764)

Donau Life A4 2-ring binder with a 30 mm spine in green is designed for orderly storage and easy access to A4 documents. The binder combines a durable outer cover with a metal two-ring mechanism to keep punched sheets secure and allow smooth page turning. Its compact A4 format fits standard documents, forms and reports, making it suitable for filing, archiving and everyday document management at the office, school or home.

Advantages

The binder's rigid cover provides protection against bending and light impacts while the 30 mm spine offers capacity for a moderate volume of punched paper. A metal two-ring mechanism ensures reliable retention and even alignment of sheets. The green finish makes files easy to identify on shelves or in boxes, and the slim A4 dimensions keep storage efficient without adding unnecessary bulk.

Suitable for

• Organising invoices, contracts and reports
• School notes, lesson plans and student assignments
• Home documents such as manuals, certificates and warranties
• Short-term archiving and project filing

Key specifications

• Ring system: 2 metal rings

How to use

Open the two-ring mechanism and align punched sheets with the rings. Close the rings until they click to secure the pages. To add or remove pages, open the rings, adjust the sheet stack and close the mechanism again. Store the binder upright on a shelf or lay it flat for transport; the rigid cover helps maintain document shape and protects contents during handling.

Usage recommendations

For long-term storage, avoid overfilling beyond the 30 mm capacity and keep the binder away from extreme humidity and direct sunlight. Use standard A4 punched paper or adapters for different hole patterns to preserve the ring mechanism and ensure even alignment of documents.
