Swirling veins of turquoise, cyan, and white flow across deep navy and black in a liquid marble composition that suggests movement frozen mid-action. The undulating patterns evoke flowing water or cosmic forces, with lighter striations rising and falling through darker depths to create a mesmerizing sense of depth and motion. 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.
