This belonged to my mother. It was found while cleaning out the family home. It's probably about 50 years old. Size: Approximately 3.5cm tall, 5.5cm wide, and up to 1cm thick. Weight: Approximately 15g (Please allow for some error as this was measured on a household scale). The pin on the back has a vintage look to it (see photo 2). Please refrain from purchasing if you are looking for perfection, as this is a used item that has been stored for a long time by a private individual. Please consider purchasing only if you understand this. Today, January 9th (Friday) until 23:59, it will be significantly price-reduced from 15,000 yen to 9,999 yen. This is the final price.
