A repeating pattern of interlocking three-dimensional cubes fills the composition, rendered in bold black and crisp white with precise linear hatching that creates depth and dimension across the entire surface. The tessellating forms establish a hypnotic optical rhythm, where positive and negative space work in counterbalance to suggest movement and spatial complexity. 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.
