These are a recorder twin set: Bressan (alto recorder) and Stinby Junior (soprano recorder). I received this recorder twin set from a senior colleague, and they were mostly unused, so they are in overall unused condition. The soprano recorder is missing the top and bottom caps of the middle joint. I cleaned them, but I haven't test-played them, but I think they should be fine. I hope someone who will use them can take them. According to Zen-On's website, the Bressan is no longer in stock. There are no instruction manuals included. If purchased separately new, they seem to cost over 3000 yen and over 2000 yen, respectively.
