Flowing ribbons of opal-inspired color swirl across the composition in undulating waves, blending blues, purples, golds, and corals into a liquid, iridescent landscape. The seamless pattern creates an endless sense of movement, with each curve melting into the next like light refracting through gemstone surfaces. 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.
