So pretty much, what you do is first apply the base color and let it dry. (im guessing you can use any nail polish brand and color of your choice as the "magic" works with the cracked finish polish) Next, you apply the cracked finish enamel polish and wait for it to dry. As it dries, the color will start to "crack" which results in cracked nails! Lastly of course, when you're satisfied with the cracks on your nail (more cracks appear as it dries) you apply the top coat. This is how mine turned out!
