Have you tried Piggy Paint nail polish yet? It’s a non-toxic, water based nail polish that’s virtually odorless. I own a few colors, and there really is not much of a smell to it, unlike every other nail polish out there (even the less toxic ones).
This nail polish would be great for those with chemical sensitivities (really, we’re all sensitive, some of us just notice it more than others) and especially for kids!
