Illustrated Envelopes C6

Our illustrated C6 envelopes turn an everyday letter into a small surprise — each design set to match the mood of what is inside. The thirty styles run from soft botanical watercolours to black-and-white adventure scenes, gentle animal characters, and cozy food sketches, so you can pair the envelope with a thank-you note, a birthday card, a postcrossing exchange, or a handwritten hello. Pick the one that fits your next letter.
