Oil slick iridescence flows across the textured surface of abalone shell, revealing layers of emerald green, violet, bronze, and blue that shift and overlap like liquid light. The composition captures the organic, undulating patterns of mother-of-pearl in close detail, where each curve and ridge catches light to create a mesmerizing depth of color and movement. 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.
