Four smooth river stones are stacked in careful balance against a textured gray wall, rendered in grayscale with soft shadows that emphasize their rounded forms. The composition uses a geometric black and white striped base that grounds the precarious stack, creating tension between the organic shapes of the stones and the ordered lines beneath. 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.
