This two case inro from the 19th century Edo period, signed by Kanshosai, exemplifies the refined decorative arts of Japanese lacquerware during Japan's final feudal era. The piece features meticulously rendered prawn and shellfish motifs, likely executed in gold and colored lacquer techniques typical of inro design, which were functional containers worn suspended from the obi of the kimono. Such objects demonstrate the period's sophisticated integration of practicality and artistic excellence, with their small scale belying extraordinary technical skill and aesthetic refinement.
