Oh Nfu, your flakies are so pretty, especially over black. Nicole by OPI Razzle Dazzler is a great black for layering. It's very pigmented and the brush is great (I hate accidently painting my cuticles with a very dark color). I used one coat of Razzle Dazzler and two coats of Nfu-Oh #49 for this mani. It's super funky!
