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. 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.
