Folder corner binder Herma Eckspannermappe Tiere "Bienenwiese" – cardboard, DIN A3, 3 inner flaps (model 19635)

Herma Eckspannermappe Tiere "Bienenwiese" is a cardboard corner binder designed for DIN A3 documents. The folder holds sheets by securing their corners with reinforced corner flaps and includes three inner flaps to improve retention and organization of large-format papers such as posters, drawings and certificates. Its flat profile and lightweight cardboard construction make it suitable for filing, archiving and transporting single or a small set of A3 sheets without adding bulk.

Advantages

The corner binder offers a simple, low-weight solution to protect A3 sheets at the corners while keeping most of the document surface visible. Reinforced corner pockets and three inner flaps increase stability and reduce the risk of sheets slipping out during handling. The cardboard material provides basic protection against folding and minor surface damage while remaining easy to store and recycle.

Suitable for (tasks / use cases)

• Transporting and presenting A3 posters and prints
• Storing drawings, blueprints or architectural sketches
• Protecting certificates, diplomas or single-page documents in A3 format
• Temporary archiving and filing in folders or document racks

When it may not be suitable

This corner binder is designed for single sheets or a small group of thin A3 documents; it is not intended for thick stacks or heavy materials. Cardboard offers only basic protection, so it may not be suitable where water resistance, heavy-duty impact protection or long-term archival preservation under controlled conditions are required.

Key specifications

• Format compatibility: DIN A3 (297 x 420 mm)
• Material: cardboard
• Design: corner binder with reinforced corner pockets
• Inner retention: 3 inner flaps for additional holding
• Profile: slim, flat design suitable for storage and transport

How to use

Place the A3 sheet into the folder by sliding each corner into the reinforced corner pockets so the document sits flat against the board. Use the three inner flaps to tuck in additional corners or edges for improved retention and alignment. Close and handle the folder by supporting it along the long edge when carrying to reduce bending. Store the folder flat in a shelf, drawer or document rack to keep contents protected and prevent warping.

What to consider before purchase

• Intended load: suitable for single sheets or thin stacks, not for thick bundles
• Protection level: basic protection from folding and minor wear, not water- or impact-proof
• Format fit: made for DIN A3 size—verify document dimensions before buying

Usage recommendations

For best results, combine the corner binder with a protective sleeve for moisture-sensitive documents or use a rigid transport box when moving multiple folders to maintain flatness and avoid edge damage.
