Height: Approximately 2.1cm Width: Approximately 2.8cm This is a valuable eraser I obtained about 40 years ago from a gachapon machine or something similar. It's rare just for its TV screen design, but the screen inside actually moves when you slide it! I believe it's a ship moving. Please compare the first and second photos. This eraser was a rare item back then, and owning one made you a hero. It's quite old, so there's some soiling, but I think it's a valuable item, so how about it? Since it's a high-value item, I will send it via Takkyubin Compact delivery service.
