Ring binder LEITZ 42380089 A4 polypropylene, 32 mm spine, black, 257×314 mm

LEITZ ring binder 42380089 is an A4 document folder made from polypropylene (PP) with a 32 mm spine capacity and external dimensions of 257 × 314 mm. The black binder uses metal rings to secure punched documents and provides protection from dust and light moisture, making it suitable for everyday filing, archiving reports and organising presentations. The textured matt finish and minimalist design from the Cosy Range give a neutral, professional appearance while remaining durable for frequent handling.

Advantages

This polypropylene ring binder combines lightweight construction with tear- and moisture-resistant material for reliable document protection. The 32 mm spine accommodates an ample number of punched sheets while metal rings ensure secure fastening and smooth opening and closing. The black matt surface resists visible wear and keeps a tidy appearance in shared workspaces. External dimensions slightly larger than A4 provide edge protection for documents and make it compatible with standard filing systems.

Suitable for

• Office filing and everyday document organisation
• Storing reports, manuals and presentation materials
• Archiving meeting notes, invoices and project documentation
• Home office use and portable document transport

How to use

Open the metal ring mechanism and insert documents that have been punched to the corresponding ring spacing. Close the rings until they click to secure the pages.

The binder can be placed on shelves or stored in filing cabinets; its slightly larger external dimensions protect sheet edges when moving between locations.

Usage recommendations

For longer-term archiving, use acid-free punched paper and avoid overfilling beyond the 32 mm spine capacity to maintain ring alignment and prevent damage to documents. Wipe the polypropylene surface with a soft, damp cloth to remove dust; avoid abrasive cleaners and prolonged exposure to direct sunlight to preserve the matt finish.
