A single neuron extends from a central soma with delicate branching dendrites radiating outward in precise, organic lines against a warm cream ground. The ink drawing captures the intricate architecture of neural pathways with scientific clarity and minimalist elegance, rendered in the distinctive observational style of early neuroanatomy illustration. 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.
