I got 2 of the Nails Inc. Magnetic Polish in my stocking this year. Here is Trafalgar Square.
This colour is really gorgeous with the magnetic effect and without.
I did find that it chipped easily but I only had a basecoat, 2 coats of polish, and one coat of SV on. Baking cupcakes, cookies, and then doing the dishes was NOT manicure friendly. This manicure didn't last nearly long enough :( but I can't wait to try it again.
You'll also notice the remnants of my snow manicure all over my skin. Too excited about this one I guess.
