I don't know why I don't own more Sleek polishes, because the 2 that I have dry really really quickly and the colours are very pretty.
This is the Sleek polish by itself:
I decided that I wanted to use Prismatic White by Essence(LE) over a colour and tried some out on a piece of paper:
Over Sleek Poion Ivy, wsith flash:
And some duochrome shots:
I like the effect Prismatic White has on this dark green polish, and I'll probably apply it on a different colour soon. :)n
