China Glaze Instant Chemistry.
My biggest problem was actually centring the magnet above each nail so that the star design I chose would be in the middle of each nail. As you can see, I only really succeeded with my middle finger. My pinkie was appalling and I managed to touch the wet polish with the magnet on the thumb (on both hands, mind you). Still, with a bit of practise, I'm sure I can get this looking amazing.
I chose the star pattern out of the three available.
So have any of you guys tried magnetic nail polish yet? What do you think? I hope your attempts worked out better than mine, but gee it's fun just giving it a go! I hope to do this again soon (after I wear all my other new polishes, of course) with a much improved result.
