Yuzu-en Alarm Clock This is a non-commercial item that I won in a raffle. It is a spring-wound clock, not battery-powered. It actually works! Although it doesn't have a box, it's in pretty good condition! I think there is no dirt or rust. It's rare to find one in such a clean condition, so if you're looking for one, please consider it. You can also set the alarm! It's cute just to look at. Please refrain from purchasing if you are concerned, as it is a home-kept item.
