How to use

Insert A4 documents into the folder so that the spine supports the stack; use an adhesive label or pencil to mark contents on the cover if needed. Store the folders upright on shelves or flat in boxes to prevent bending. When transporting, place folders inside a briefcase or a document bag to protect edges and keep pages aligned. For heavier stacks, reinforce the spine with an additional sleeve or place between rigid boards to maintain shape.

Usage recommendations

For best results, avoid prolonged exposure to moisture and direct sunlight to preserve the paper cover. Use colour-coded folders to separate projects or years, and combine with labelled dividers for faster retrieval of documents.
