This is an authentic nickel-plated brass travel soap box from the "Nippon Era." The front lip is clearly stamped with "NIPPON," a mark used exclusively for Japanese exports between 1891 and 1921. Unlike silver, which tarnishes black, this box features a durable nickel plating that has maintained its luster for over a century. You can see the original brass base metal peeking through on high-wear areas, adding a wonderful "shabby chic" or historical character to the piece. Era: Vintage / Antique (Nippon Era, 1891–1921). Material: Nickel-plated brass with a sturdy rear hinge. Why it was made: These were essential personal accessories for travelers, businessmen, and even military personnel as "private purchase" gear to carry bar soap cleanly in a travel bag or kit. Condition: Good vintage condition. The plating shows honest wear consistent with its age, revealing the warm brass underneath. The hinge remains fully functional.
