## Long description

Donau Master 2-ring A4 ring binder with a 75 mm spine in black is a robust document organiser designed for storing punched A4 sheets. The binder accommodates a large volume of paperwork while maintaining a slim, professional appearance. It features two metal rings aligned for standard two-hole punched documents and a durable cover that protects contents from dust and light wear.
Advantages
The 75 mm spine provides substantial capacity for reports, manuals and multi-page documents without excessive bulk. The two-ring mechanism is simple to operate for quick insertion and removal of punched sheets, helping to streamline filing tasks. The black cover offers a neutral, office-appropriate look and the construction is intended to keep documents flat and protected during regular use.

Key specifications
Format compatibility: A4 punched sheets (two-hole)
Spine width: 75 mm capacity for thick document sets
Ring type: two metal rings suitable for standard two-hole punches

How to use
Open the binder rings using the ring-release mechanism, align punched sheets with the rings and close the mechanism to secure the pages. Place assembled documents on a shelf or in storage with the spine facing outward for easy identification. For heavier document sets, support the binder vertically or lay it flat to prevent strain on the rings and cover.
Usage recommendations
To maximise longevity, avoid overfilling beyond the 75 mm spine capacity, use standard two-hole punched paper, and store the binder away from prolonged direct sunlight and moisture. Periodically check the ring mechanism for proper alignment to ensure smooth opening and closing.
