Finely crafted silver boxes called bonbonnieres, after the French word, were given as mementos to invited guests of Imperial banquets and state ceremonies from the late 1800s. Today, the custom of giving presentation boxes is not limited to the Imperial family, but has been adopted by corporations and ordinary people to commemorate the founding of a company or a wedding, or an auspicious event. This fan shaped box has three Myoga (Zingiber) design crests on the lid.
