This should explain it. http://aussiegirlblogs.blogspot.com/2011/06/nails-inc-magnetic-polish.html
I don't like Nails Inc - I'm an OPI girl.That said I cannot bear the OPI shatters - and prefer the look of this magnetic.But in all honesty I'm too old as well!!!!
Just started using Nails Inc. very impressed, stays on longer than some of the other brands.
