This was purchased as a set in the early 1980's at a party that sold gifts and dishes, etc from Japan. This little set, I was told, represents a man and a woman. They are both ceramic and the lids are a hard plastic. The tall one is approximately 3 1/2 inches tall and 2 ½ inches wide. The smaller jar is just under 3 ½ inches tall and less than 2 inches wide. There is no design on the back of either. The writing underneath is written in another language, but wanted to include this information for the pictures.
