I have a hard time resisting a nice black glitter. I think it's my weakness. I'll probably end up frankening one myself when I find a good black glitter that doesn't bleed. In Icing Twilight's case it's not the glitter pieces that are black, it's the base, but I love it nonetheless.
Twilight is a black jelly/cream based polish packed full of fine holographic silver glitters. I think it'd be a great polish to use when doing an "outerspace" themed manicure. It just looks like the night sky plastered on your nail! The formula for this polish had a good consistency and went on more like a cream than it did a glitter, which was excellent. It also only needed 2 coats for full coverage.
I only have a couple other Icing polishes, and I really like all of them, but this one is probably my favorite! Have you guys tried this one or picked it up yet?
