Stylized horseshoe crabs in gradient pink, blue, and cyan float across a deep charcoal background, each creature rendered with a rounded shell, delicate spines, and a gentle smile. Rainbow-striped pearl shapes orbit around them like playful celestial bodies, creating a whimsical nocturnal scene with a soft, contemporary illustration aesthetic. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
