Shares of Chinese toy maker Pop Mart International Group Ltd. rose the most in nearly four months on Wednesday, after founder and Chief Executive Officer Wang Ning said the company could easily surpass its annual sales projection and announced plans to launch a new mini Labubu doll.

The CPSC says the fake Labubu plush figures and plush key chains are small enough that a young child could put one in their mouth and block their airway, creating a risk of choking and death. The agency also reported instances of the counterfeit toys breaking apart and releasing small pieces that could become ingestion or choking hazards.
