Chrome Mirror powder is a pigment that produces metallic effect when applied on top of your nail polish color.
The powder takes on a different color depending on the base color polish you are wearing.
Black base color is likely to give the most striking results.
Once sealed with a top coat, the powder stays on and can withstand water, oils, soap etc. until it is removed with nail polish remover/acetone.
