It is sheer after 1 coat but opaque with 2.
I personally would not wear a plain black polish but this is OK as the glitter brightens it up a lot.
This was a typical Jessica formula but strangely it stunk to high heaven which I have never noticed before with any other Jessica polish...weird!
The brush is great and I have not done any clean-up whatsoever on these pictures.
This is 2 coats plus base and top coat.
