I was going to throw this away since I don't use it, but after looking it up, it seems to be a product exclusive to onboard sales on sightseeing trains. I'm listing it in case anyone needs it. I received this from a friend around 2023. It's been stored at home, but it's unopened and unused. I'm a beginner on Mercari, so I apologize if there are any mistakes in the transaction. I will do my best to be polite.
