For Day 3, I`m assuming it`s your favorite makeup brush, and this is mine! It`s from Bare Minerals, and I don`t remember the cost, but I don`t think they sell this exact one anymore.. but I`m sure you can find on like this! :)
I use this brush to blend out any shadows I put in my crease, and in my opinion, it works really well! I`ll be honest! I don`t have the biggest makeup or brush collection, and I don`t own very many high end products, but this is my favorite brush that I`ve used!
