This is a keychain (keyring) I received at the Tokyo International Fire Exhibition. I went with my daughter, who loves emergency vehicles, and received two, this is one of them. It's new and unused. It was unopened, but I opened it to take photos. It comes with a box, but the box has some slight warping. It's probably made of stainless steel and is durable and sturdy. Also, the design is sophisticated, and can be used by children and adults alike.
