Just the black that I needed. I do my nails as a hobby and was looking for a good black nail polish that was opaque with just one layer for doing designs and such. Saw lots of reviews that the Onyx Black from OPI was just what I needed, so I gave it a whirl and it works! One layer and it's completely opaque so it's perfect for patterns and designs. Came in a timely manner as well. I had just bought two other OPI colors from a shop that day so I felt spoiled.
This is a good, deep black nail polish.
