Five lunar phases are arranged vertically in grayscale, progressing from a thin crescent through waxing and full moon to waning crescent, rendered in soft watercolor with delicate gradations of black and gray. The composition is centered and meditative, with each celestial body slightly varied in detail and tone against a clean white ground. 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.
