This is a ticket holder with a Kominato Railway strap. I received it in October 2021 during a lottery-won tour of the Goi Engine Depot during the COVID-19 pandemic. However, it doesn't seem to be a limited edition, as it's sold in the shop. I checked online when listing it, and it's 500 yen. Please consider it as a good deal, as you won't have to pay for shipping... It's unused, but it didn't come with any packaging originally. I've cut and inserted graph paper to make the size easier to see for the listing.
