How to use

Fold your A4 document into DIN Long format so the recipient address aligns with the window. Insert the folded document into the envelope until the address is visible through the window.

Verify the address visibility and seal integrity before placing envelopes into postal trays or mail bins.

Usage recommendations

Avoid overfilling the envelope to prevent bending or obscuring the address. Store envelopes in a dry, flat place to maintain adhesive performance and paper integrity.
