How to use

Slide A4 documents into the open side of the sleeve so the document lies flat and is fully covered by the transparent film. Use the colored edge to quickly identify and group related documents. Insert sleeves into ring binders or folders as needed; the thin polypropylene construction allows multiple sleeves to be stored together without significantly increasing bulk. For frequent handling, ensure documents are aligned before insertion to avoid creases.

Usage recommendations

Store sleeves flat in a dry, cool place to maintain flexibility and prevent warping. For long-term archival of important documents, pair sleeves with acid-free paper and avoid prolonged exposure to direct sunlight to reduce potential fading. When inserting fragile or very thin papers, consider adding a backing sheet to reduce shifting.
