Pvc toys are poisonous. If you have children at home, don't play pvc toys with them without supervision.
As long as it is pvc, it is polymer, and these materials are not toxic by themselves. But when these things are synthesized and processed, it is inevitable that some additives will be added to the project. These additives are small molecules that can be absorbed by the human body, which is the so-called poison source. High temperature will produce toxic substances, and fire inspection prohibits the use of PVC materials for indoor decoration.
