How to use

Insert the document or card into the envelope so that the address area remains visible for printing or hand-writing. If the envelope has a gummed flap, moisten the adhesive evenly and press firmly to seal; if it has a peel-and-seal strip, remove the protective backing and press to close. For machine processing, align inserts and avoid overstuffing to ensure reliable feeding through printers and inserters.

Usage recommendations

Store envelopes flat in a dry, cool place away from direct sunlight and moisture to prevent warping or adhesive degradation. For professional mailings, test feed a small batch through your printer or inserter to confirm compatibility and print alignment before processing the full pack.
