Inside the double-walled glass structure, there is water and Japanese gold and silver leaf. It's a set of gold and silver. When you hold it in your hand, the gold leaf shimmers gently with the water, making it a very beautiful sake cup. Craftsmen with limited skills make each one by hand. It is a special sake cup perfect for celebrating special occasions. It is also sold at the Japanese museum shop of "MoMA" (Museum of Modern Art, New York).
