A detailed celestial map fills a circle, crowded with stars and constellation lines rendered in black ink against weathered cream paper. The composition evokes historic astronomical charts, with precise linework showing the interconnected patterns of northern sky, aging gracefully across a textured, aged surface. 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.
