So this is a thing, and since it was on sale at the local beauty supplies shop, I caved and bought a bottle and one of the little magnets the other day.
After playing with that one bottle, I went back and bought it in every single color they had while it was on sale. Damn, ladies, this is the coolest thing that you can apply to your nails. And I sound like a cyborg, too, when I describe how I got the effect on my nails.
Now all I think about is how badass a car would look covered in this stuff.
On the other hand, I'm sort of disappointed that I didn't get super powers from it. If they marketed nail polish to guys, they'd need to have a disclaimer: "This product does not turn you into Magneto. You will not have the power to single-handedly destroy electronics at will. Sorry."
