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. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
