This is a neriko (kneaded incense) container from Kyukyodo, but it's perfect as a guinomi (sake cup). It was very dirty, so I boiled and cleaned it. I believe it's from the Showa era. Diameter: Approximately 5.3cm Height: Approximately 5.5cm Sizes are approximate. The actual item may differ slightly in color from the images. It's an old item, so there are age-related scratches and stains. There are small scratches visible in the images.
