I am a very big fan of Real Technique brushes and featured products. I also have many expensive brand brushes to which I do not often reach as this. This brush is my favorite. The brush hairs are more tightly, which facilitates precise application. Especially for something more viscous Foundations as Mac's Studio Finish a great brush. The dense but also good for contouring or for Blush. When traveling, it is always there because it is so versatile. Have more than one stand with me on the dressing table.
