Quick Take: natural hair, soft bristles
If you've ever used a Shu Uemura brush, then you know what outstanding quality they are. The Natural Brush 4F is another great Shu Uemura brush. I use this brush to apply eyeshadow in those hard to reach places like the corners of the eyes and for lining my eyes. This brush applies cake and cream eyeliner like a charm. I also use this brush for blending. This brush has many uses and it's worth every penny.
