How to use
Insert documents or paper items into the open-top sleeve with the printed or important side facing the clear surface for immediate visibility. For best fit, use A4 sleeves for full sheets without folding, and select smaller sizes for receipts, index cards or folded pages. Stack or file sleeves vertically or horizontally as needed, and avoid overfilling to prevent stretching or damaging the sleeve seams. Clean the surface with a soft damp cloth if necessary.
Usage recommendations
Store in a dry, cool place away from direct sunlight to prevent material warping or discoloration. Use appropriate sizes for each document to maintain sleeve shape and ensure readable labels. For long-term archival storage, combine these sleeves with acid-free backing or folders if paper longevity is a priority.
