Interlocking rounded U-shapes and arches layer across a black field in strict geometric repetition, creating a rhythmic optical pattern that alternates between negative and positive space. The crisp black lines on cream grounds build a hypnotic visual rhythm typical of midcentury modernist abstraction, evoking both architectural precision and organic undulation. 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.
