Tangled networks of hand-drawn nerve fibers in black, blue, and green sweep across a warm cream and coral dotted ground, mapping the intricate pathways of neural tissue with the precision of scientific observation. The composition captures both the methodical beauty of biological study and the organic chaos of interconnected synapses, rendered in bold strokes that honor the pioneering work of early neuroscience. 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.
