An inro is a traditional Japanese case used to hold small items, such as medicine or cosmetics. Typically made of lacquered wood, inro consist of several stacked compartments that are secured with a cord. They often feature intricate designs and are worn suspended from the obi, or sash, of a kimono. Inro originated during the Edo period (1603-1868) and were popular among the samurai class. They are often adorned with decorative elements, including netsuke, which are small carvings used to secure the inro to the wearer's clothing. Today, inro are appreciated as art objects and collectibles.
