I've painted these over a base coat of my favourite pale nude - Jack Wills blush as I thought each of the different coloured glitters would show up well on it. I'm sure this would work equally well over a really dark or black polish.
Shades L - R - Green - Copper - Blue - Gold - Pink. There's also a silver crackle glitter in the range.
I already had the green crackle colour and wore it in this post over a green polish for a Christmassy look.
The polishes didn't crackle a massive amount when I used them, but I think this is because I used quite a thick coat - generally a thinner coat gives a bigger crackle effect with these types of polish. I also quite like these as glitters without the crackle effect and I've heard you can lose it by letting the polish dry out a little - this can happen naturally over time anyway but can also be fixed by adding a little polish thinner. My tops tips for the day right there ha!
These are such a bargain at £2.99 each compared to the price of some other brands that have brought out crackles, and it's nice to see a different take on the trend with the addition of the glitter. The gold one is my favourite :)
