This is a small lidded bowl from Kinshobai. I believe it's the container that comes with Kinshobai gifts for the mid-year or year-end holidays. It's not new, but I think it would be great for holding classic tsukudani (preserved foods), pickled plums, or even candies and small items. The lid is not airtight, it just sits on top. It's mostly unused, but it's old, so there are some scratches and stains on the bottom. If you understand this, please consider using it.
