This set of solid sterling silver with gold overlay and black enamel cuff links were made in Japan prior to World War II. This set measures 3/4 inch square and they are in good working order. The box is in very good shape considering the age. The box is made from wood with a faux alligator skin exterior and a silk interior. The box has the original brass hinges. The style is very Japanese - with Mt. Fuji, a Pagoda and Cherry Blossoms hand engraved on the front.
