A figure-eight or infinity symbol rendered in concentric rings of red, orange, and deep teal swirls against a black ground, creating a hypnotic, tunnel-like effect that seems to pulse forward. The layered, curved lines form a mesmerizing kinetic rhythm that draws the eye inward, evoking both retro op-art sensibilities and the electric glow of neon. 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.
