NARS has a "new" eyeshadow hybrid on the market. I use quotes with the word new, because it seems that everyone is putting out these cream/ powder hybrid products lately. That is great news for me, as I am having fun trying them all!
Callisto is not my favorite. It tends to look too glittery, even when used dry. I do experience fallout, and when used wet, it becomes too metallic for my taste.
Subra is pretty, and works most excellently as a liner when used wet. It is not a new color for me though.
Overall, I have mixed feeling about NARS Dual Intensity shadows. I like Desdemona and Subra, but Callisto was far too glittery for me. I will wait and see the rest in person before ordering any more. I would love to see how Phoebe and Dione perform in person.
