Concentric rings in chartreuse yellow form a repeating geometric pattern across a black ground, evoking the atomic age aesthetic of 1950s artwork. The precise, mechanical stacking of rounded rectangles creates a hypnotic rhythm that feels both retro and timeless, with clean lines and bold color contrast defining the composition. 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.
