From L-R we have: Barry M Pink Nail Effects (Pink Fizz NP 314) and Barry M Black Nail Effects (Black Magic NP 311).
I alternated the colours.
How cool does that yellow/black combo look! These is something appealing about the yellow/pink too.
(Didn't mean this one to look so rude - soz.)
The crackle nail varnishes are pretty cool I think. They don't last as long and tend to be a bit duller (matte I guess) but I'm not that fussed about using a shiny top coat.
Both these cost £3.99 from Superdrug. And VERY cool.
