Undulating ribbons of black and cream weave through the composition in a continuous, flowing rhythm that recalls 1970s liquid artwork and op-art sensibilities. The organic curves and bold contrast create a hypnotic, almost liquid movement across the surface, with no clear beginning or end to the pattern's dance. 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.
