Black Onyx® is a classic black nail lacquer from OPI, delivering a deep, glossy finish that complements any look. This professional-grade polish offers salon-quality color and coverage for a timeless, elegant manicure.
Glides on like a dream in just one coat, and that mirror-like shine really lasts for days without chipping. I've been getting compliments everywhere I go.
This black polish has the most intense, glass-like shine I've seen from a drugstore lacquer. Two thin coats gave me perfect, streak-free coverage that lasted a full week without chipping.
The brush applies the polish so smoothly that I got a perfectly even coat on every nail without any streaks. After two thin layers the finish is genuinely glossy and deep, and it’s held up chip-free for four days so far. Exactly the classic black I needed for a clean, professional look.
Finally, a black that doesn't need three coats—two gave me that deep, glossy finish and it's still chip-free after a week.
I was hoping for a true one-coat black, and this delivers that deep obsidian gloss beautifully. It's thick enough to self-level without dragging, though I needed two thin coats for my impatient self. The finish is genuinely glossy and lasts about six days before chipping on me.
This one-coat black actually delivers full opacity, which is rare for a deep shade like this. The glossy finish stays shiny for about three days before I notice any tip wear.
The black is a true, solid shade after two coats, which is nice, but the brush is a bit too narrow for quick application. It chips after about three days for me, so it's okay for the price but nothing special.
