Eli K. ★★★★★

I’ve tried plenty of black polishes, but this one’s coverage is honestly a game-changer—two thin coats and it’s completely opaque. The brush spreads the lacquer evenly, so I didn’t have to fiddle with streaks at all.

Zoe O. ★★★★★

This is the first black polish I’ve tried that actually looks wet and glossy after just two coats. The coverage is so even that I skipped a top coat, and it still lasted a full week without chipping.

Ava ★★★★★

The brush applies so smoothly that even my non-dominant hand got a clean edge on the first try, and the deep shine looks like I just left the salon. It's lasted four days without a single chip, which is better than any other black polish I've tried.
