How to use

Insert documents or booklets up to the stated dimensions through the open side and adjust the edge so the contents are held securely. Ensure papers are aligned within the sleeve to avoid creasing.

When preparing multiple items for storage or shipping, group items in separate sleeves to maintain clarity and protect edges.

Usage recommendations

Store sleeves flat or upright in a dry environment away from direct sunlight and high heat to prevent deformation. Clean with a soft cloth; avoid abrasive cleaners or solvents that can damage the transparent material. Use the adjustable edge to match document thickness and replace sleeves that show signs of wear or edge separation to preserve archive-quality protection.
