A whimsical algebraic equation unfolds across a cream ground, with zebras substituted playfully into each line of mathematical notation to transform abstract symbols into living creatures. The monochromatic pen illustration progresses from a formal formula at top through increasingly chaotic simplifications, culminating in three striped zebras standing side by side as the final punchline. 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.
