MAC Duchess Eyeshadow Quad ($44.00 for 0.19 oz.) contains three limited edition shades and one permanent shade. It's from the upcoming MAC x Osbournes collaboration collection. The textures of the eyeshadows in this quad were fairly good, with the matte shade being a little drier and harder to blend on the skin. All four shades work well together, but there have been many warm-toned quads like it before, so it may also be more dupable depending on what products you already have.
