OPI Black Onyx Nail Lacquer – Crème Black Nail Polish, 0.5 fl oz | Fast-Drying, Chip-Resistant Shine

OPI Black Onyx is a rich, opaque crème black nail lacquer that delivers salon-quality shine and up to 7 days of chip-resistant wear when used with OPI’s recommended base and top coat.

This classic black from OPI’s Nail Lacquer line offers a deep, even crème finish ideal for solo looks or as a base for nail art. Formulated for smooth application with a pro-wide brush, Black Onyx dries quickly and provides reliable coverage in two coats. The formula is vegan and part of a palette of over 200 trend-forward shades made in the USA.

How opaque and smooth is Black Onyx on the first coat?

Black Onyx lays down dense, streak-free color with excellent pigment saturation. Many users will see strong coverage after one coat, but two coats ensure full opacity and an even crème finish.

• Highly pigmented crème formula for deep black color
• Pro-wide brush minimizes streaks and speeds application
• Recommended two-coat application for uniform opacity

Will this polish last through daily wear without chipping?

When you apply OPI Natural Base Coat, two coats of Black Onyx, and finish with OPI Top Coat or RapiDry Top Coat, the system helps resist chips and maintain shine for up to seven days for many users. Actual wear time varies with activities and nail prep.

• System-tested for up to 7 days of wear using a 3-step routine
• Fast-drying, salon-quality finish reduces smudges
• Removes cleanly with standard lacquer removers like Expert Touch

How do I apply and remove Black Onyx for best results?

Start with clean, dry nails and apply OPI Natural Base Coat to protect the nail plate and improve adhesion. Apply two thin coats of Black Onyx, allowing short drying time between coats, and lock in shine with OPI Top Coat or RapiDry.

• Prep: file, push back cuticles, and remove oils
• Application: base coat → two thin color coats → top coat
• Removal: use an acetone or non-acetone lacquer remover like Expert Touch

Is Black Onyx suitable for nail art and layering?

The deep, uniform black of Black Onyx makes it a versatile backdrop for stamping, decals, and hand-painted designs. It also layers well under sheer glitters or thin top coats for custom finishes without losing depth.

• Perfect as a base for contrasting nail art and metallics
• Works well with gel top coats and varnish overlays
• Compatible with creative techniques like stamping and negative-space designs

Who is this for: OPI Black Onyx is designed for anyone who wants a dependable, salon-quality black polish—whether you prefer classic, minimalist manicures or use black as a creative canvas for nail art. It’s a solid pick for home mani enthusiasts, professional technicians, and shoppers seeking a long-wearing, fast-drying crème black in a 0.5 fl oz size.
