This is a souvenir from Kochi. The skipjack tuna on the left is the kind that makes a "poo" sound when you squeeze it. It hasn't been used, but it has been stored in a desk drawer in this condition. The metal parts have some tarnish from storage, but I wiped them clean. They're not perfect, though. They would probably look even better if polished more carefully. It's not rust. It's thick, so it can't be sent via Nekopos (a Japanese postal service).
