Black organic shapes splatter and pool across a bright yellow-amber ground, creating an abstract tortoiseshell effect that evokes molten lava or burnt organic matter. The irregular patches vary dramatically in scale and density, building an energetic, almost chaotic composition that feels both natural and intensely graphic. 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.
