How to use

Insert B5-sized documents or folded A4 sheets into the envelope, align contents within the gray preprint area if required for addressing or window alignment, and seal according to the envelope’s closure type. Use suitable addressing methods such as handwriting, labels, or a printer that aligns with the preprinted zone. Ensure contents are flat and protected to avoid creasing during handling.

Usage recommendations

Store envelopes in a dry, cool place away from direct sunlight and humidity to maintain paper quality. When printing addresses or labels, perform a test print to confirm alignment with the gray preprint area. For important documents, consider additional protection such as an inner sleeve or card stiffener if extra rigidity is needed for mailing.
