Deep emerald and bright lime green layers ripple and swirl across the composition in organic, undulating bands that evoke the natural striations found in malachite stone. The concentric patterns build from darker zones into luminous highlights, creating a hypnotic depth that feels both geological and otherworldly. 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.
