This is a Christmas seal from the Korean National Tuberculosis Association, featuring a Pororo design from 2011. It seems to be a product that, when placed in a location emitting electromagnetic waves, is supposed to block those waves. It says "24K GOLD Pure Gold Plating" in Korean. For those who like it, how about adding it to your collection? It is an unused item, but it has been stored for a long time. The backing card has some damage. Please check the condition carefully in the photos. We appreciate your purchase if you don't mind the aging and deterioration. Pororo, Crong, Harry
