A grid of detailed anatomical illustrations displays the inner systems of the human body in precise black ink against a clean white ground. Bones, organs, and skeletal structures are rendered with scientific accuracy in a classical engraving style, arranged like specimens in a natural history collection. 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.
