Kat Von D Shadow Box is a slightly warm-toned, dark taupe with a matte finish. It is a discontinued eyeshadow.
Shadow Box is described as a "matte chocolate." It's a deep, dark brown with warm, red undertones and a matte finish. It had good color payoff, and the texture was finely-milled, velvety, and soft. It wasn't powdery, but it seemed a little thin. This shade managed to last for eight and a half hours on me. See comparison swatches / view dupes.
