Excellent for applying highlighter. Photo Comparison with the Contour Brush from the Core Collection Kit.

The brush takes color beautifully, and this is also very well. He swallows the color does not like other brushes. Even after repeated use, the brush hairs are not glued or so.
On the YouTube channel of Pixiwoo and Real Techniques and other Youtube channels you can get suggestions for the benefit of the brush. For me, another plus

SETTING BRUSH
The brush is soft bound and pleasantly soft on the skin. Slightly tapering at the top.
I've been using the brush for applying the powder or Baked Highlighter. (Oval bond length hair lace 25mm / side 23mm, width below 10mm / 7mm widest 20mm / 15mm)

In order to estimate the size of the brush better I added a photo comparison with the Contour Brush from the Core Collection Kit.
