Bio DoUgh is a natural, scented modelling dough made and sourced in Australia. It is also an Australian family owned business. All ingredients are food graded. Flour Salt Oil... So in case a child eats it by mistake it is harmless. The lab test proved that Bio Dough is as safe as food. That said Bio Dough is a TOY not food. The taste is too salty to discourage consumption as mentioned on the packaging! It has a 2 years shelf life if left unopened. Once used it could to be kept for 6 months.
