It's true. Cotton dolls come from different manufacturers, and manufacturers must attach the production date, anti-counterfeiting standard answers and product certificate to their products, so as to prevent unscrupulous merchants from shoddy, confusing the real with the fake, disrupting the market and harming the interests of the broad masses of the people. Products without production date, anti-counterfeiting trademark and product certificate cannot be accepted by the masses, so dolls must have ID cards.
