Trish McEvoy
#11 Flat Eyeliner BrushLining your eyes can be tricky, especially if you don't have the right brush. Trish McEvoy #11 Flat Eyeliner Brush makes applying eyeliner easy. Simply look down and work the brush across the top lash line using a "push" motion for a clean line, or use it to "smudge" powder around the entire eye for a smoky look. The #11 Brush is synthetic and can be used wet or dry.
Origins

NARS
Flat Concealer BrushMany concealer brushes are too small to do the job. This flat brush is the perfect size to evenly apply concealer to the under eye area, the eyelids and the base of the nose (this area is often a bit red and can use cooling down). Made with nylon, this brush is gentle enough to use on the delicate areas around the eye.
Paula Dorf

The foundation brush is made of Taklon, a man-made fiber that allows better control and creates less waste. Application is easy; simply brush on makeup using downward strokes for flawless, even coverage.
