A symmetrical anatomical illustration of a human rib cage rendered in crisp white against a soft gray ground, each bone defined with clean, precise lines and subtle internal shading. The composition centers the sternum vertically while the ribs curve outward in balanced pairs, creating a geometric yet organic rhythm that feels both clinical and meditative. 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.
