## Long description

Donau Premium lever A4 75 mm navy blue is a lever-operated ring binder designed to store and organise A4 documents with a spine capacity of up to 75 mm. The binder has a durable cover and a metal lever mechanism that allows for smooth opening and secure closing of the rings, providing reliable handling for frequent filing tasks at home, in the office, or on the move.
Advantages
The lever mechanism ensures effortless and fast opening and closing of the metal rings, reducing wear on papers and enabling quick insertion or removal of documents. The 75 mm spine capacity accommodates large volumes of paper, reports or project documentation while keeping pages flat and accessible. The durable cover resists daily wear and maintains a professional appearance in navy blue, and the metal rings provide stable alignment and long-term reliability.

Key specifications
Format: A4
Spine capacity: 75 mm
Closure type: lever-operated metal ring mechanism
Cover material: durable laminated board (rigid cover)
Number of rings: metal D- or O-shaped rings for stable page alignment
Colour: navy blue
How to use
Open the lever to release the metal rings, place punched A4 sheets onto the rings and close the lever until it locks to secure the documents. For best results, align punched holes before inserting pages to avoid bending or misplacement. Use dividers or labelled separators to organise sections and maintain easy access to frequently used documents.
Usage recommendations
Store the binder upright on a shelf or in a filing cabinet to preserve the cover shape and ring alignment. Avoid overfilling beyond the 75 mm capacity and distribute heavy contents evenly; use sheet protectors for loose or fragile pages and keep the lever mechanism clean of debris for long-term reliable operation.
