DIA50-120xH35-65mm, China
This series of 10 cups make a good set of sake cups for dinner party. Depending on their drinking ability, guests can pick the size of their own cups and the host can refill all their cups at the same time!
The cups are so precisely made that they can be nested into one and other like the Russian Matryoshka dolls, making storage much easier.
