## Long description

Donau 4-ring A4 binder with a 40 mm spine in blue is a practical document organiser designed for A4 paper. The binder uses a four-ring mechanism to secure punched sheets, dividers and plastic sleeves, providing stable storage for reports, presentations and reference materials. Its 40 mm spine offers capacity for a substantial number of pages while keeping documents accessible for frequent use in office, school or home environments.
Advantages
The binder combines a durable cover with a standard four-ring mechanism that ensures reliable sheet retention and easy page turning. The 40 mm spine increases storage capacity without adding unnecessary bulk, and the blue finish provides a professional, neutral appearance suitable for various settings. Compatibility with standard punched sheets, index dividers and plastic pockets makes it a flexible solution for organising and archiving documents.

Key specifications
Format: A4
Ring system: Four-ring mechanism
Spine width: 40 mm
Colour: Blue
Compatible contents: Punched sheets, index dividers, plastic sleeves
How to use
Open the rings using the mechanism release, insert punched A4 sheets, dividers or plastic sleeves, and close the rings until they click to secure the contents. For best alignment, insert pages so the punched holes sit evenly along the rings and add dividers to separate sections. To remove or rearrange pages, open the rings, reposition sheets and close the mechanism firmly. Use the spine to label the binder for fast identification when stored on a shelf.
Usage recommendations
Store the binder upright on a shelf to maintain shape and prevent warping of the spine. Avoid overfilling beyond the 40 mm capacity to reduce stress on the ring mechanism and covers. For long-term archiving, combine with acid-free sleeves or sheets to protect important documents.
