The crystal finish maintains legibility of printed text and preserves photographs, certificates and important papers in daily use, filing systems and presentation materials.

With a thickness of 150 µm each sleeve offers stable support for single sheets and small document sets while remaining flexible enough for easy insertion and removal. The clear surface ensures that document details remain readable without removing them from the sleeve and the supplied box keeps the pack organized for convenient storage and distribution.

How to use

Insert A4 documents into the sleeve opening, ensuring edges align with the sleeve borders to maintain protection. For best results, slide documents in slowly to avoid folding or trapping air bubbles. Use the sleeves individually or together in folders and binders; when placing multiple sleeves in a binder, check compatibility with the binder's sleeve retention system. Store unused sleeves flat in the box to prevent warping.

Usage recommendations

For long-term document preservation avoid exposure to direct sunlight and extreme temperatures. Clean sleeves with a soft, dry cloth; do not use solvents or abrasive cleaners. When protecting archival or valuable materials, consider using sleeves along with acid-free backing sheets or archival folders.
