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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
