The Ninja had thought it was impossible. She hasn't really seen a great black glitter polish. She's seen some good ones, but for the most part black pigments seem to eat glitter. Especially fine glitter.
Enter stage right: Nfu-oh GS-14
An inky black lacquer with gobs of fine holographic glitter.
She is understated in that dark polish way, yet once the spotlight hits her she simply lights up!
Let The Ninja be clear: this is not a holo polish. It is not solid hologram. It's definitely a black polish with small (eensey!) holo bits.
Let's take a look:
Application is, as with all Nfu-oh enamels, flawless. Since The Ninja can't just pick them up at Ulta (they are an Asian brand; she purchases from Fabuloustreet) she tends to hoard them.
In order to extend the life of this one, she applied it over a black cream, Illamasqua Boosh. The swatches are one coat of GS-14 over 1 coat of Boosh. She tried Gs-14 on its own and two layers were opaque.
