How to use

Insert the A5 document or folded A4 sheet into the envelope, align contents to avoid bulging, then remove the protective strip from the silicone tape and press the flap firmly to seal.

Usage recommendations

For reliable mailing results, use these envelopes for single- or double-sheet documents and standard-sized inserts. When printing addresses directly on the surface, use ink and printer settings suitable for 90 g/m² paper. Store unopened packs in a dry, cool place away from direct sunlight to preserve the adhesive tape and paper quality.
