A black and white checkerboard pattern ripples and warps across the composition as if the grid itself is breathing or bending through invisible currents. The regular squares distort into organic, undulating waves, creating a hypnotic optical effect that draws the eye across the entire surface with fluid, almost liquid movement. 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.
