This is a Tokyu Corporation keychain. It's a commemorative keychain for the 100th anniversary of the Setagaya Line. I received it at an event. It wasn't for sale, and the staff said they only prepared about 1,000 of them. I think it's rare because it's an anniversary item. I would be happy to pass it on to someone who likes the Tokyu Line or the Setagaya Line. Bulk purchases are welcome! Please also check out my other listings.
