Binder STARPAK A4 50 mm blue (model 133271) — ring binder for A4 documents

STARPAK A4 50 mm ring binder in blue is designed to store and organize A4 documents with a 50 mm spine capacity. The binder features a standard three-ring mechanism and a durable cover that protects punched papers, reports and manuals from wear. Its simple construction allows for convenient insertion and removal of pages while keeping documents aligned and accessible.

Advantages

The binder offers reliable document retention through a standard ring closure that holds punched sheets securely. Its 50 mm spine provides substantial storage for multiple documents without excessive thickness, and the hard-wearing cover helps protect contents from bending and surface damage. The blue finish makes it easy to visually identify or color-code folders for filing systems in offices, schools or at home.

Key specifications

• Format compatibility: A4 documents
• Spine capacity: 50 mm
• Closure type: standard ring mechanism (three-ring style)
• Cover: rigid/durable protective cover

How to use

Open the ring mechanism and align punched pages with the rings. Insert pages one by one or using a stack, then close the rings until they click to ensure sheets are secured. To add or remove pages, press the ring release tabs or gently pull the rings apart as designed, keeping pressure even to avoid misalignment. Store the binder upright on shelves or lay flat for transport; ensure bulky contents are distributed evenly to maintain shape and function.

Usage recommendations

For long-term storage, avoid overfilling beyond the 50 mm capacity to prevent strain on the rings and cover. Use pre-punched A4 paper or a hole punch compatible with the ring spacing. Label the spine or front cover for quick identification and keep the binder away from prolonged exposure to moisture or direct sunlight to preserve the material and color.
