The Mac 275 Medium Angled Shading Brush is probably one of the most universal make-up brushes in the entire collection. It is made of natural pony hair and is very soft to touch. It is easy to clean and dries out fast. I found that this brush is perfect for highlighting the brow bone area. However, since it allows to apply shadow under by controlling the angle and, hence, the thickness of line and intensity of application, I think using only this brush will allow you to do the entire makeup. You can use it to apply all over lid color. It is also perfect for using in the crease and outer corner. The slanted side allows you to effortlessly glide it along the crease to ensure flawless application.
Ideally, I try to keep several copies of the brushes that I love and constantly keep in rotation, because I can dedicate a separate brush for lighter, medium and darker shades and get several good uses of them prior to washing. That definitely prolongs the brush life and keeps it in good shape. The brush is available at a very attractive price point, considering its quality and the fact that it is made of natural hair. The Mac 275 Medium Angled Shading Brush is one of my most favorite MAC Cosmetics brushes and because of its universal quality, I would highly recommend to to both professional make-up artists and beginners who are just starting to build their makeup brushes collection.
