## Long description

Donau Master lever-arch A4 ring binder with a 75 mm spine is designed for organised storage of punched A4 documents. The binder combines a robust cover in gray with a lever-arch mechanism that opens and closes smoothly to allow quick insertion and secure retention of sheets. Its 75 mm capacity accommodates substantial document sets for office, school or home use while maintaining an orderly filing system.
Advantages
The lever-arch mechanism offers reliable, easy operation, reducing the effort needed to add or remove pages.

How to use
Open the lever-arch mechanism by lifting the lever to release the rings, insert punched sheets onto the rings and close the lever until it locks to secure the contents. For even distribution and smoother closure, align punched holes carefully before closing. Use the spine for labeling to identify the binder contents on shelves.

Store the binder upright on shelves to prevent warping and avoid overfilling beyond the 75 mm capacity to maintain the mechanism’s longevity. For important or frequently handled documents, place dividers or plastic sleeves inside to reduce wear on punched edges.
