Break the law. It is illegal to sell wands secretly. Since fairy sticks belong to fireworks rather than candles, operators engaged in fireworks retail must obtain a fireworks business license, and illegal fireworks business is suspected of illegal business. Even if it is not sold but given away, fairy wand is not a product that can directly contact with food. During the burning process, black spots will fall on the surface of the cake. If food safety problems are caused, the consequences will be unimaginable.
