A densely branching neuron fills the composition with intricate black line work against a warm cream ground, its delicate dendrites spreading outward in organic, fractal-like patterns that suggest both botanical growth and electrical impulse. The scientific precision of the rendering conveys the wonder of neural architecture, capturing the microscopic complexity of the brain with the hand of a naturalist-anatomist. 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.
