Concentric rectangular lines radiate outward from a central vertical axis, creating a symmetrical pattern that oscillates between advance and recession. The composition is rendered entirely in black ink on white, with thousands of precise parallel lines building an optical illusion of depth and movement that appears to breathe. 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.
