Rare Final Price Yokohama Royal Park Hotel Keychain

Purchased at the Royal Park Hotel in Yokohama several years ago. This is a key-shaped keychain from that time.
It has never been used and has been stored in a dark place with its outer cover still attached. Since it hasn't been used, it is a new, unused item. It is in beautiful condition.

Please refrain from purchasing if you are sensitive about long-term personal storage.
