This is a wine cup made from solid Yakusugi cedar. It features the beautiful, intricate grain unique to Yakusugi cedar, which is over 1,000 years old. Because its growth is extremely slow, the annual rings are tightly packed, creating a distinctive wood grain pattern. The felling of Yakusugi cedar was banned in 2001, and this item is believed to be made from wood felled before that time or from naturally fallen trees. The word "Miyazaki" is carved on the bottom. As this is a natural wood product, the use of dishwashers and dryers is not recommended. ※This description includes AI-generated content.
