Concentric curved lines spiral inward toward a central point, creating a mesmerizing tree-ring or fingerprint pattern rendered entirely in bold black strokes against a cream ground. The organic, hand-drawn quality of each undulating line conveys both meditative repetition and natural growth, with the composition building intensity as it moves from the irregular edges toward the precise geometric center. 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.
