Thoughtful materials & print quality

We chose 350 gsm cover stock for its smooth surface and substantial hand. Compared to typical thin postcards, this paper weight provides less show-through and a satisfying, premium snap when you flick the edge. Colors stay punchy, lines remain crisp, and the card stands up to handling—exactly what you want from a floral postcard that may travel far to reach someone special.

If you’re into swaps, it’s a charming mail art piece that holds up beautifully.
