We only work with pigments that have low or no known toxicity when properly used.  We do not work with cadmiums, cobalts, lead, manganese, mercury, or arsenic pigments.  We do work with copper-containing pigments, which are generally not considered non-toxic, but pose no serious health risks, especially when handled as intended.Please note that our line of watercolors is professional/artist grade and not intended for children.  Pans pose a choking hazard.  Please use only as intended.
