So, I rushed home, removed my Zoya mani (which came off very easily and cleanly...add me to the "I love Zoya" band-wagon), And put on the white base coat:
I guess Pure Ice wants you to buy other colors, and then fill in the white areas with those for a complete design. So, my final verdict is that it was really fun to watch the design appear, but I would rather just use my own pretty polishes under my own black crackle. Each set is like $7.00, and it was thoroughly entertaining!
Will you be trying these out?
