Ring Binder Donau Master lever A5 75 mm blue — Donau DONA0170

Donau Master lever A5 ring binder with a 75 mm spine in blue is designed for organised storage of punched documents in A5 format. The binder features a lever-operated ring mechanism that allows easy opening and secure closing, enabling insertion and removal of multiple sheets, reports or invoices. Its 75 mm spine provides capacity for large volumes of paperwork while maintaining a compact A5 footprint suitable for desks, shelves and archive boxes.

Advantages

The lever-operated mechanism ensures smooth, low-force opening and precise alignment of the rings for reliable document retention. A 75 mm spine delivers high capacity without significantly increasing shelf depth. The A5 format and compact dimensions make the binder easy to handle and store. Durable exterior and reinforced edges improve longevity under frequent use. The blue colour aids visual organisation and quick identification among other binders.

How to use

Place A5 punched sheets onto the ring posts and operate the lever to open the rings. Arrange documents as required, then move the lever to close the rings until they align and lock securely.

Usage recommendations

Use standard A5 punched paper or tabbed dividers for best compatibility. Keep the lever clean and free of debris to preserve smooth operation. For long-term archiving, place labels on the spine and avoid extreme humidity or direct sunlight to maintain the binder's shape and colour.
