Horizontal stripes of black, light blue, and black form the structure of Chicago's iconic municipal flag, with two bold red six-pointed stars centered in the black band between the blue stripes. The composition is clean and geometric, presenting the flag's recognizable artwork with stark color contrast and symmetrical balance. 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.
