A sake set consisting of pitcher and cups, in the form of stacks of cups. The different sizes correspond to different types of drinks: one cup is a choko small glass, two cups stacked a slightly larger one, and four cups stacked a tumbler. The stack of five cups is actually a pitcher for sake. Because all of the cups have the same shape, they can be stacked together when not in use, and the one-cup choko doubles as a lid for the pitcher. When the pitcher is heated, for drinking warm sake, the cups can be warmed simultaneously, too.
