Revolution 強勢眼線液筆（毛氈筆尖）

The pen shape makes it way easier to control than those little pots, and my wing came out sharp on the first try. It survived a whole rainy commute without smudging.

The felt tip is stiff enough that I can get a sharp flick in one go, and it doesn't drag or skip like the brush pens I've tried. Wore it to a sweaty outdoor concert and the wing was still intact by midnight.

I've worn this through a full workday and a sweaty gym session and the wing didn't budge or smudge at all. The pen design makes it easy to get a thin line close to the lash line, then build it into a sharp flick.
