Ring binder Donau 2-ring A4 35 mm yellow — Donau 3732001PL-11

Donau 2-ring A4 ring binder with a 35 mm spine in yellow is designed for storing and organizing A4 documents and loose sheets. The binder uses a two-ring mechanism that secures punched paper and inserts, while its colored cover enables simple visual identification in filing systems. The 35 mm spine offers medium capacity, suitable for moderate volumes of documents in office, school, or home environments.

Advantages

The two-ring mechanism provides stable retention of punched sheets and prevents slippage during handling. The 35 mm spine balances storage capacity and compactness, allowing the binder to fit on standard shelves and in filing cabinets. The yellow cover supports color-coding workflows and quick retrieval. The cover material is durable enough for everyday use and protects contents from dust and light wear.

How to use
