Big Bang from Formula X by Sephora came home with me when I was supposed to be shopping for someone else. Once upon a time I was given advice from a lovely woman who said anytime you buy a gift for someone you should buy yourself a little something as well.Thank you Diane for the wonderful advice, you were a wise woman. Nail polish bottles are so small I had to buy several to really make it count and follow my friends advice. In the bottle Big Bang looks amazing and the first time I used it I was not disappointed. A dark and rich purple base filled with little bits of purple glitter. The formula has a great consistency not too thick but it is a little bit on the gritty side because of the glitter. It dries a little on the rough side as well so you will need top coat. Pictured above is two coats of Big Bang topped with one coat of Essie Gel Setter.
