Review of OPI Black Onyx by Picon08
A completely mediocre product. I was expecting a lovely glossy, easy to apply polish - but this is runny and gloopy at the same time. You will need at least two coats to get a good coverage. I will not comment on lasting power as this can be affected by your base & top coat. I use it on my swatch sticks (for duochromes) so that it is not a waste and will not be buying another one when (and if) it does run out. Also the price is high for me (in New Zealand dollars) when I can get a Jordana polish that is better for much less.
