OPI GelColor Black Onyx. Salon size 0.5 oz/15ml. Made in USA. Brand new, genuine.
OPI Gelcolor Soak off gel polish applies just like traditional nail polish, but gives your nails a super shiny finish that lasts up to two weeks. You just simply apply the gel like regular nail polish and cure it under a UV or LED lamp. No DBP (Dibutyl Phthalate), Toluene, and Formaldehyde. Applying OPI GelColor requires a special base coat, color, top coat, and curing light.
OPI GelColor Application:
First, apply the OPI GelColor base coat to the nails and then cure the base coat under an LED light for 30 seconds. Then apply the color layer on top of the cured base coat and cure for 30 seconds under the LED light. Finally, apply the GelColor top coat and once again cure the nails under the LED light for 30 seconds. During application, it is recommended to apply both the base coat and top coat to the free edge of the nail in order to seal the manicure.
