Smith Cosmetics 124 Contour Brush is a brush that retails for $24.00.
Smith Cosmetics 124 Contour Brush ($24.00) is a short, angled brush with rounded edges designed for applying and blending out contours. It is made out of pony hair and recommended for use with liquids, creams, and powders. The brush has a total length of 7.25 inches / 18.30 centimeters, and the brush head was in 20.00mm width, 15.0mm length, and 11.00mm thickness (at its widest/longest points). It is very similar in overall size and quality to the #122 with the major difference between the angle and roundedness along that angle that gives it more of the look you'd expect from a contour brush. That being said, it is much, much smaller than even some of my smaller contour brushes with a stronger angle and is much denser. The smaller size and greater density make it ideal for laying down precise contour or navigating on smaller features and faces. It took some getting used to, because initially, I overapplied just about every product I tried using with it! Once I played more and adjusted my application, I was able to achieve softer, smoother contours that weren't overly blown out beyond where I really wanted the contour color to be. It was easier to use with liquids/creams compared to more pigmented powder products as it was a denser brush. I also liked this brush for applying liquid foundations around the nose and underneath the eyes, as the contoured, smaller shape fit well into the nooks and crannies of my face. The brush felt soft, smooth, and didn't irritate my face; the pony hair is not as soft as the best goat or squirrel hair, though (I find the pony hair used by Smith to be as soft as the goat hair used, sometimes seemingly softer).
With densely packed pony hair and angled bristles, this brush applies and blends your contour colour in one seamless step.
