A small butterfly sits at the center of concentric, symmetrical waves that ripple outward in alternating bands of black, white, and gray. The geometric pattern creates a hypnotic op-art effect with a distinctly retro sensibility, evoking the visual language of 1970s artwork through its bold graphic simplicity and high-contrast palette. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
