I bought this Nail Polish a while ago from Sephora. Lately, it seems like there are so many different companies following the magnetic trend. I'm happy to say that I bought it before it was the "in thing".
The polish is from nails inc. The color is called Trafalgar Square. I am in love with this polish. If you don't like the design, put on another coat and hover the magnet over your nail a second time. This is so cool. I also love how it reflects when the light hits it.
