This is Aizu-nuri wooden lacquerware. It's an old item from the Showa era, used about twice and then stored at home for a long time. It was a custom order, and I believe the design is hand-painted. There are 9 lidded soup bowls and 10 sake cups. There are no noticeable scratches or stains, but I think there are some scratches from use. The bottom has a shop mark (photo ⑦).
