Interlocking transit lines in red, blue, green, purple, yellow, and cyan form a complex network across a world map, with each colored route representing different metropolitan subway systems overlaid in a single composition. The lines flow and branch organically across continents, creating a dense, interconnected visual rhythm that transforms geographic borders into a unified system of human movement and connection. 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.
