Bold black and white wavy lines flow across the composition in rhythmic, undulating patterns that seem to shift and ripple like liquid marble or topographic contours. The high-contrast strokes create an optical motion, with alternating bands of solid black and negative white space generating a hypnotic, almost three-dimensional effect. 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.
