|picnik made the blue darker than it really is :-(|
Word on the street is that White Polka Dot is an alternate name for a polish Nubar did for The Painted Nail called Moon Drop. It's not a very bright white, but neither is it quite grey; it has a very slight silvery, opaly sheen. The black one is just plain, shiny black though.
I found both these glitters a little tricky to apply. The glitter particles are quite heavy, so they sink pretty quickly, and the clear base is thick. It worked best for me when I put the cap back on and turned the bottle upside down for several seconds after every couple of nails. Slow going. But once you get it on your nails, the glitter is pretty smooth, so that's a plus.
I've got Zoya Raven and Purity on their way to me thanks to the two free polishes promo (ends tomorrow), and once they arrive I'm going to try the black and white polka-dotted mani.
