Height: 7.3cm Inner diameter: Approximately 3.5cm This is a kokeshi doll-shaped trinket box. It was popular as a gift for newborns, used to store umbilical cords, baby teeth, etc. It's made of plain wood and has a cute, rounded shape^_^ It's unused, so if anyone is looking for one, please consider it. It's from Usaburo, a workshop located near Ikaho Onsen in my hometown of Gunma Prefecture. I'd love to go and try painting one someday. If you're in the area, please check them out!
