I found these at my grandfather's house. Three "Tama-hai" cups (jade cups) Made of aluminum and treated with a special, strictly regulated alumite processing. The surface treatment uses high-level techniques reserved for high-quality products. When you pour sake, a beautiful image of a jewel is reflected. Elegant gold and black coloring. Will not peel, discolor, or scratch. Diameter: 56mm Height: 44mm The outer box has some sun damage. Please understand that these are new, unused items that have been stored at home.
