Stacked concentric U-shapes and arches in black and white create a rhythmic, interlocking grid of geometric forms that pulse with optical movement. The pattern alternates between positive and negative space, building a hypnotic composition rooted in midcentury modernist principles of symmetry and repetition. 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.
