Pretty but didn't work [SEP] This is a natural nail polish, not a gel.  Therefore, the cat-eye line does not hold.  I will work perfectly with the magnetic.  But, once the magnetic is removed and the top coat apply, the effect is lost and it will spread over the entire nail.  It still has a nice affect, but just not the cat-eye line effect.  it needs a solid dry surface to work with.  Maybe letting the black under coat completely dry before apply the magnetic polish.  Just a lot of work to achieve a simple effect.
