## Long description

Donau Master 2-ring A4 ring binder with a 75 mm spine in navy blue is designed to store and organise punched A4 documents. The binder has two round rings for secure fastening of punched sheets, a rigid 75 mm spine that supports upright storage on shelves and a durable cover suitable for frequent handling in office, school or home environments. Its dimensions accommodate standard A4 paperwork and allow collection of multiple documents, making it a practical choice for filing, archiving and project documentation.
Advantages
The binder combines a hard cover and a firm spine to keep documents flat and protected while standing on a shelf or transported. Two rings provide stable retention for punched pages and reduce the risk of sheets slipping out. The 75 mm spine offers increased capacity for thicker document sets without significantly increasing shelf width, and the navy blue finish gives a professional, neutral appearance suitable for mixed workspaces.
Suitable for
 Filing and archiving A4 documents
 Organising project documentation and reports
 School and university coursework storage
 Office records and administrative files
 Home paperwork and manuals

How to use
Open the binder rings by pulling the ring tabs or applying gentle pressure according to the ring mechanism, insert punched A4 sheets onto the rings, then close the rings securely so pages lie flat.

Use dividers or labelled separators inside the binder to structure sections and locate documents quickly.
Usage recommendations
For long-term archiving, use reinforced punched sheets or plastic sleeves to protect frequently handled pages. Label the spine clearly for quick identification on shelves and avoid overfilling the binder beyond the 75 mm capacity to maintain ring alignment and cover integrity.
