Old iron sake cup. Its origin is unknown. There's no oily smell, and I suspect it was actually used as a sake cup. It's rusty, but not crumbling, and the surface is smooth. As it's old iron, there are some chipped areas as shown in the images. Please be aware of this beforehand. This is a very appealing piece of old iron. Diameter: Approximately 7.5cm Height: Approximately 1.7cm Sizes are approximate. The actual item may differ slightly in color from the images.
