Ring binder Pagna 30503-01 Black

The Pagna 30503-01 ring binder in black is a leather-covered document folder with a round-ring mechanism designed for organized paper storage. Measuring 295 mm wide, 360 mm deep and 50 mm high, the binder accommodates letter- and A4-sized documents and provides a slim profile suitable for shelves and filing systems. This single-piece binder combines durable outer material with a practical internal ring system to keep punched documents secure and accessible.

Advantages

The binder’s leather cover offers a durable, easy-to-clean surface that resists wear from daily handling. Its round-ring mechanism allows smooth opening and closing for adding or removing pages, while the 50 mm spine provides capacity for a moderate volume of documents without becoming bulky. The neutral black finish integrates well in professional environments and home offices, and the dimensions are compatible with standard A4 filing and storage solutions.

Suitable for

• Organizing A4 and letter-sized documents
• Presentation folders for meetings and reports
• Archiving invoices, contracts and project files
• Home office filing and personal record keeping

Key specifications

• Cover material: leather finish
• Ring type: round-ring mechanism
• External dimensions (W × D × H): 295 mm × 360 mm × 50 mm
• Color: black

How to use

Open the round-ring mechanism using the release tabs or levers, insert punched documents onto the rings and close the mechanism until it clicks to hold pages securely. Place document dividers or transparent sleeves if separate sections or protection for frequently used pages are required. Store the binder upright on a shelf or flat in a drawer, keeping it away from prolonged direct sunlight and moisture to preserve the leather surface.

Usage recommendations

For best longevity, avoid overfilling beyond the spine capacity and clean the leather cover with a soft, slightly damp cloth. Use standard hole-punched paper to prevent ring misalignment and distribute heavy contents across multiple binders when archiving large volumes.
