The 56 mm spine provides a compact footprint for A3 binders yet holds up to 500 sheets, and the robust construction helps protect edges and corners of stored documents. The neutral black design is compatible with a wide range of office decors and provides a professional appearance without adding bulk.

How to use

Handle the binder by its edges to minimise wear on corners and maintain the shape of stored papers.

Usage recommendations

Store the binder upright on a shelf to prevent bending of A3 sheets, avoid prolonged exposure to moisture, and keep away from direct heat to preserve the cardboard structure. For archival storage, combine with protective sleeves for individual pages to reduce abrasion and ensure longer document life.
