I just bought this and I LOVE it. It's so easy to fill in your eyebrows and keep it looking totally groomed and natural. I have dark hair and light eyebrows and I constantly struggle with filling them in with something that looks natural AND still looks groomed. This fits the bill totally. A little goes a long way too. One of the circles is a wax and the other two are slightly different shades of powder. You dip the brush in the wax and then in the powder and apply it.
