A dense network of colored lines intersects across a white ground, each route labeled with Japanese characters and station names in a geometric grid pattern. The composition uses red, green, blue, yellow, and pink lines to distinguish different transit routes, creating an intricate system map that reads as both functional diagram and visual complexity. 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.
