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 (using a household scale, so please allow for some error). The pin on the back has a vintage look (see photo 2). Please refrain from purchasing if you are looking for a perfect item, 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.
