The tea caddy is a box for holding the set of tools needed to perform the tea ceremony outdoors. The exterior of the lid and the four sides are decorated with a continuous pattern of stripes. The stripes are composed of foreign designs such as Namban arabesque, wave patterns, strung pearl patterns, and sawtooth patterns executed in hiramaki-e, mother-of-pearl, and inlaid metal on black lacquer. The striped pattern became fashionable when foreign traders brought in striped fabrics from Southeast Asia in the Momoyama and early Edo periods. As a design favored by the foreigners, the stripes were widely adopted for dyeing and weaving, pottery, and lacquerware.
