Bold black and white wavy lines flow across the composition in rhythmic, undulating patterns that seem to shift and ripple like liquid marble or topographic contours. The high-contrast strokes create an optical motion, with alternating bands of solid black and negative white space generating a hypnotic, almost three-dimensional effect. 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.
