Icing’s MagnetiX Nail Polish. This doesn’t have a specific color name, but it’s a metallic blue and when you expose it to the magnet, purple lines come out.
It was kind of hard to get a detailed picture, but in person the effect is a lot more noticeable. It’s just soft waves of a darker color that come out of the base color.
As far as I can tell, this polish operates just as well as those you would find in Sephora, and it’s more than half the price! It covers in one coat and is, surprisingly, easy to use.
I also have one that is silver, so I’m hoping that effect will be a bit more noticeable and I’ll be able to upload some more drastic pictures for you guys to see.
All in all, I definitely recommend this polish!
