Technical details of the opaque black C5 window envelopes

These envelopes are made from high-quality paper with a rich black print covering the entire exterior. To ensure that the contents are completely opaque, the envelope features a gray interior lining that, combined with the dark exterior color, provides maximum opacity. Handling is made easy by the convenient adhesive strip on the straight flap: simply peel off the protective strip, press firmly, and the envelope is securely sealed.
