Another possibility is that the jewelry you bought in Mengjinyuan may be a product jointly launched by Leofoo and Mengjinyuan. In this case, the steel seal tag of Mengjinyuan shows that the logo of Leofoo was decided by both parties, so as to show that the product was produced by two companies. In this case, brochures or official channels usually provide information about cooperation. If you still have questions about this, I suggest you contact the customer service department of Mengjinyuan or Leofoo for more details.
