This is a novelty item, a "Suica's Penguin" pin badge, issued by JR East's Omiya Branch. I received it about 10 years ago from a friend who was a train conductor. - Design: A pin badge of a Shinkansen (bullet train) with a penguin on it. - Material: Metal - Size: Please refer to the image. It has aged over the years and has yellowed slightly due to storage, but it is unused. Thank you for looking.
