Revlon. It's their Crackle Effect Perfectly Paired Duos nail polishes. Each set comes w/2 coordinating polishes: one is a regular polish & the opposite end is the crackle polish.

Personally, I've yet to get in on this trend, but I'd like to try it. I think what sparked my interest in this nail trend was a video I saw on youtube. I wish I could remember who it was, but they used a gradient of orange, yellow, & red w/a black crackle polish on top & it gave the effect of molten lava underneath w/black crusted lava on top. I thought that was an ingenious way to wear the crackle trend.
So, what do you think of the crackle nail trend? Do you think you'll haul some of Revlon's new crackle polish? Share your thoughts in the comments! :)
