Smith Cosmetics 230 Quill Crease Brush Small is a brush that retails for $24.00.
Smith Cosmetics 230 Quill Crease Brush Small Brush ($24.00) is a small, rounded crease brush that doesn't flare out much from the ferrule. It is made out of goat hair and is designed to be used with powder products. The brush has a total length of 6.90 inches / 17.50 centimeters, and the brush head was in 16.00mm width, 12.00mm length, and 7.00mm thickness (at its widest/longest points). The goat hair used in the crease brushes seemed softer to me than what was used in the face brushes. It worked well for applying more intense color into the very depths of the crease for me, which gave a more precise, defined lay down of color. For someone with smaller eyes, it could function the way more common creases brushes do without applying color far past the crease area. Of all the brushes from Smith, this one (along with the #232) didn't retain its shape as well after washing, so they became more rounded and less pointed after the first wash.
Designed to apply and blend eyeshadow into the crease, this brush is made from the highest quality soft natural goat hair. Its smaller size and pointed tip make it the ideal tool for detailed crease work and smaller or deep-set eyes.
