This item has been stored at my parents' house for a long time. All items have a "r." mark on the back. Since my parents collected Rune Naito items, I suspect these are Rune Naito pieces, but I'm not entirely sure. If anyone knows more about these, and if you understand that the manufacturer is unknown and the condition is poor, please purchase. Because they are white plates, the damage is not captured well in the photos. Also, since there is a limit of 20 images, I couldn't take close-up photos of everything. Please refrain from purchasing if you are concerned about minor details, as this item has been stored by a private individual.
