Anyone who knows me and reads my blog knows I am obsessed with Nail Varnish. Well today I discovered a new Nail Varnish which is part of the Katy Perry OPI collaboration collection. It is called Black Shatter and it creates a cracked effect that can look slightly like leopard print. I think it is amazing and it works really quickly which is very impressive. It isn't out until 1st January 2011 so it will be on my wish list for the new year. I can't wait. Thanks to the OPI youtube channel you can check out a video of how it works below.
