Ryu Jung-ha, CEO of Creatorslab,
was teaching "non-toxic clay" with children.
That time a child playing on clay
had a red rash on his hand.
A child kept complaining of pain and itching,
and at that time she felt frustrated and sorry
because she didn't know what the problem was.
So she found a problem with the harmfulness of toys.
She was so worried about the health
and safety of children when I saw them
trying to take clay to their mouths.
