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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
