Have been using this for 4 years and it's great for filling those brows in! I use it with the Anastasia brow whiz (after lining) and it will last for years. I make sure to replace according to the label expiration date.
I've been using this brow shaper for almost 2 decades since high school and I probably will never stop. Natural and buildable color, and 1 of these will last YEARS.
This brow shaper is the only one that looks natural. I've been using it for probably twenty years -- nice to have so many color choices. The brushes really last a long time!
