This is a keyholder from the Tohoku Shinkansen in the 1980s. I found it while organizing the desk I used as a child. The keyholder itself is made of metal and is from that time. The ring and carabiner were replaced with new ones for this listing. The condition of the front has some dirt and scratches that are difficult to see in the photos. The back is rough. It's in good condition considering its age. It will be shipped via Rakuraku Mercari delivery in a cardboard box. Please feel free to comment if you have any questions.
