Blue Metallic Flakies

Hey There! I've been experimenting with Blue Metallic Flakies and am thinking of adding them to my nail polish line! This would be a metallic flakie topcoat series in different colors. I used one coat of this flakie polish over a coat of black nail polish. What do you think? The metallic vibrance is more vivid in person! And I've been getting a ton of compliments so this experiment may be here to stay! :D
