Why is that fanned out paintbrush included in nail art paintbrush sets? I don't know what it's official use is. If you do, please leave a comment explaining it to me. I tried it out and made this. Maybe that's it's intended use. I started with a white polish and used turquoise acrylic paint and the fanned out paintbrush to go in at different angles.
This is left to a matte finish:
Then I added a coat of Sinful Colors Pearl Harbor which has a pretty awesome blue/green glitter. It's hard to photograph.
This is just a quick swatch of Pearl Harbor over white and black respectively.
