Sixteen colorful sea slugs arranged in a 4x4 grid float across a soft pink background, each creature rendered in bright pastels with distinct patterns, spots, and color combinations. The playful illustration style emphasizes rounded forms and cheerful hues, creating a whimsical underwater collection that feels both scientifically inspired and purely imaginative. 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.
