Since I started my non-toxic movement at our house, its been over a year since my toes have been painted. When I stumbled upon Piggy Paint, my heart leaped for joy! Is non-toxic, doesn't smell (it smells like art paints), and is kid friendly. I ordered some for myself and am happy with the results. One thicker coat has stayed on for about 4 days so far without rubbing or chipping off. I would have waited to do a more thorough review, but they are offing a great deal right now for facebook fans, so I wanted to spread the word! This is the set I got. I love the colors!
