Kids should not be using adult nail polish because it is full of toxic chemicals that penetrate the nail into the blood stream. Kids nail polish should also not last any longer than a day on kid's nails because it will prevent their nails from breathing and being healthy. We have selected kid's nail polishes that are as natural as possible and non toxic, water soluble or peelable. S'N'BIO is a new, plant-based nail polish made with natural origin ingredients. Nailmatic kids nail polish is specially formulated for kids and is free from phthalates, formaldehyde and fragrance.
