I am a huge fan of this angled brush from Sigma. I had been searching for a super precise brush I could use for creating winged eyeliner looks with gel liner. All the drug store brushes I purchased were too thick and messy, which did not give me the control I needed to draw a clean line.
The E65 allows me or draw the perfect, precise line. Winged eyeliner has never been easier to apply. Using a brush and gel liner also seems to help guarantee that the two wings match.
