Present corporate stationery, direct-mail campaigns or brand guidelines with polished realism. This 6000 × 4000 px PSD delivers two high-resolution C4 envelope mockups—front flap-open view and clean back view. Every envelope, highlight and shadow sits on its own layer, so you can reposition, recolour* or soften ambience in seconds. Insert your artwork via Smart Objects, save, and export crisp previews for client decks, press kits or e-shop thumbnails.
