It is important to know

When choosing a Herltz U A3 file folder, it is crucial to consider the method and scope of use - the folder is primarily intended to protect individual or smaller sets of documents from creasing and allows basic visual separation of content. Before purchasing, it is worth considering whether this type of folder will suit your typical archiving procedures and whether you need additional closing options or greater robustness for frequent transportation.

• U-shaped folders allow for quick insertion and removal of individual sheets, but are less suitable for larger quantities of documents or frequent carrying.
• The A3 format makes sense when you regularly work on technical drawings or larger projects, otherwise it can take up more space than classic A4 folders.
• For mobile use or transportation, it is recommended to choose a folder with a closure (e.g., elastic or clip), as open folders do not protect the contents from accidental movement.
• Due to their simple design, these folders are most useful for short-term organization, preparing materials for meetings, or quick internal reviews.

In practice

🟢 Organization of individual documents

The folder is very suitable for separating and protecting individual contracts, plans or materials in A3 format.

🟡 Use for archiving larger amounts of material

Suitable with limitations - it protects individual documents, but for larger archives or frequent interventions, we recommend more robust and closed folders.

🔴 Transfer multiple documents between locations

Less convenient – the open design does not prevent the contents from slipping out of the folder, which can be a problem when carrying.
