For today I have one of Zoya's Pixie Dust matte glitter polishes.
Nyx - From the Pixie Dust collection - This is a slate blue matte base with silver glitter. Good application and coverage. While similar to OPI Liquid Sand its different enough that I wouldn't compare them.
Kristen - This is a light grayish blue creme. This is a very nice color. A bit sheer but opaque in two-three coats.
Kristen topped with Out The Door. No top coat on Nyx.
