What material is the hand-made model made of? Are there any substances harmful to human body?

About the toxicity of hand-made materials, it mainly refers to the volatiles when PVC materials are not shaped when the mold is turned over and injected. If you buy a finished white mold, you basically don't have to consider the toxicity of the material. Like other plastic products that come into contact with life. Paint is really toxic when sprayed, but it won't affect your health if you protect it. Keep ventilated and wear a mask. After all, it is not mass production.
