I first saw this crackle nail polish on a relative of mines, and my first thoughts were "wow that's different!" She had her mani/pedi polished in black with the white crackle polish and it looked like lightning bolts at first site, but when I got closer I could see the details in the crackles. I really like this nail polish, and it's becoming more and more popular so if you're looking to get this on your nails I would first go to a professional nail shop, and after you see the polish you can purchase a bottle from the nail shop. If you just want to do it yourself try your local beauty supply store for the polish, and have fun!
