As you can see the crackle look blue, black and grey before
After shaking and rolling it It looks completely black.
This is Cover Girl Boo Hou! They are other colors all seem to be Halloween themed.
Didn't think they would work but as you can see they did!
Here it is on my test wheel over different polishes. It actually worked best with the Cover Girl polish it came with which was the light frosty yellow Cover Girl Sunkissed. It took a while for it to finish cracking all the way but it was super strong after it didn't flake off like my other crackle polishes. It didn't even need a top coat it was strong and shiny.
So if you have a Dollar Tree near by please go check it out its great to own old polishes like these since everyone seems to be making them now. I actually cant wait to get the OPI black shatter and the China Glaze crackle collection to be released!
