Now you see it.... now you don't!
I used a temperature-change polish from Born Pretty Store and Zoya Perrie to create this look.
When it is warm, the thermal polish is nearly the same color as the Zoya, so the water marble design disappears and only shows up when my nails are cold!
Thermals are so much fun to play with, I'm loving creating hidden designs with them and another matching, regular polish (I did some invisible stamping with the same polishes here)!
