These C4 envelopes are made from materials sourced from sustainable forestry. The left-side film window, measuring 45 x 100 mm, displays the recipient's address, which is either pre-printed on the letter or on the document itself. The envelopes are securely sealed with a reliable adhesive that acts like a seal, protecting the contents from prying eyes. Any attempt to open the envelope would be immediately noticeable.
