White mathematical formulas, diagrams, and scientific notation densely cover a deep navy blue ground in an all-over pattern that suggests a chalkboard or blueprint. The composition radiates intellectual energy through its layered complexity, with equations, geometric shapes, and sketched figures creating a rich visual texture of pure scientific inquiry. 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.
