Honestly, I doubted how necessary this brush really was. I I thought for sure I could do the same contouring with my small brush. Wow, was I wrong! I'm so glad I finally decided to try it. It takes 2 seconds for me to easily get the look I want now. It's so quick and easy to use, and enables me to make a contour in my crease and corner that's perfect. Much better than my old way. Great tool! I love it!
