Thank you for viewing. This is a commemorative medal from Tokyo Shibaura Electric Co., Ltd. Noticeable dirt and scratches (see photos). Material is unknown. It did not react to a magnet. The color may differ between the photo and the actual item. Please be aware that there may be differences in size or image. I am not negotiating prices. Shipping is planned via Yu-Packet Post Mini, but the shipping method may change. Old newspapers, plastic bags, and waste materials may be used as cushioning materials. Please do not mistake them for trash.
