DIN C5 Self-Adhesive Envelopes with Window, Red Print

Make a statement: DIN C5 envelopes in bright red with a window

Make your correspondence stand out. A bold red symbolizes energy and attention—ideal for drawing the recipient’s focus directly to important messages or high-impact promotional mailings. These colorful window envelopes offer a rare combination of functional efficiency and emotional impact. Thanks to the window on the left side, your mail always looks highly professional, while the bold color ensures that your letter is guaranteed not to remain unopened in the pile. These red envelopes are perfect for everything from exclusive promotional offers and club newsletters to festive invitations designed to make a clear statement even before they’re opened.

Technical Precision of the Red C5 Window Envelopes

These envelopes are made from high-quality white paper with a rich red print covering the entire exterior. To ensure the confidentiality of your documents, the envelope features a gray interior lining that completely obscures the contents. Handling in everyday office use is incredibly easy thanks to the modern pressure-sensitive adhesive: simply peel off the protective strip on the straight flap, press down, and your mailing is securely sealed. Our product range also includes matching red C4 envelopes with windows as well as a wide range of classic C5 mailing envelopes in many other colors.
