Seven sleek bullet trains in profile stack diagonally across a bright yellow ground, each rendered in clean lines with distinct livery colors ranging from turquoise and white to blue and orange. The composition celebrates the evolution of Japan's iconic Shinkansen rail system through a minimalist, graphic approach that emphasizes speed and engineering precision. 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.
