A checkerboard pattern of black and white squares warps and undulates across the composition, creating the illusion of a curved, three-dimensional surface that seems to breathe and shift. The geometric precision of the grid contrasts with the fluid distortion, producing a hypnotic optical effect that draws the eye inward. 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.
