The U.S. Consumer Product Safety Commission issued an “urgent” warning Monday about knockoff Labubu dolls posing a “serious risk of choking and death to young children.” The warning only applies to fake versions of the Labubu dolls — sometimes referred to as “Lafufu dolls” — which are sold as tiny plush figures on keychains.

According to the Consumer Product Safety Commission, the fraudulent dolls can break apart easily and are small enough to lead to choking hazards.
