Although it's no longer available now, This is a prize from Yoshinoya's stamp card campaign. It was not for sale, and it was gold only for this particular time, making it rare, I think. At the time of the application, it was said to be "pure gold used." As you can see in the photo, the entire picture part is gold. Thank you. Material: Porcelain (Ceramic) Plates/Bowls/Dessert Dishes
