Three koi fish swim and leap through a dark midnight ground, their bodies rendered in warm cream, rust, and burgundy tones with delicate gold leaf accents that catch the light. Water plants and rounded stones anchor the composition, creating a sense of serene movement within an intimate aquatic world painted with the precision and richness of traditional East Asian art. 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.
