This is a sake cup I purchased several years ago. It's unused, but has been stored for a long time. It comes with a box and instructions. 【Details】 Koji Kamada is a highly renowned artist, famous for his tenmoku glaze sake cups, and is known to have been mentored by Living National Treasure, Uichi Shimizu. His works using tenmoku oil drop glaze are highly regarded overseas, and have become increasingly popular in China in recent years, making them difficult to obtain. The various patterns created using the tenmoku glaze are all breathtakingly beautiful, reminiscent of the stars in the galaxy. How enchanting it would be to pour sake into such a vessel and watch the surface of the liquid gently sway in the light.
