A sake set consists of the flask and cups used to serve sake. Sake sets are commonly ceramic, but may be wood, lacquered wood, glass or plastic. The flask and cups may be sold individually or as a set.

A cup is an open-top container used to hold liquids for pouring or drinking. Although mainly used for drinking, it also can be used to store solids for pouring. Cups may be made of glass, metal, china, pottery, wood, stone, bone, polystyrene, plastic, aluminium or other materials, and are usually fixed with stem, handles, or other adornments, though a beaker has no handle or stem. Cups are used for quenching thirst across a wide range of cultures and social classes, and different styles of cups may be used for different liquids or in different situations. Cups of different styles may be used for different types of liquids or other foodstuffs, in different situations, or for decoration.
