Tea cup made in Japan

A yunomi (Japanese: 湯 の み) is a form of teacup, usually made from a ceramic material, taller than it is wide, with a cut or turned foot. Unlike the more formal chawan tea bowl used in the Japanese tea ceremony, yunomi is made for drinking tea daily (or informally).
There are special pairs of yunomi called meoto yunomi (meoto means "married couple"). The Meoto yunomi usually consists of two cups with the same pattern (sometimes different colors) but different sizes and often slightly different shapes (the larger cup being the “husband” and the smaller one being the “wife”).
Many contemporary potters, both in the East and the West, make yunomi which has become a very collectable item.
