Although they're no longer available now, This is a prize from Yoshinoya's stamp card. It's not for sale, and it's usually not gold, but it was specially gold this time, so I think it's rare. At the time of application, it was said to be "pure gold used." As you can see in the photo, the picture part is all gold. Please feel free to ask if you have any questions. Thank you. Material: Porcelain (Ceramic) Dishes/Bowls/Dessert dishes: Pair (2)
