This item was found while organizing, and the details are unknown. I also have no knowledge about this item. Based on the size and photos, I believe it might be a HAKUBA 2-way level, but I would appreciate it if those who are knowledgeable could examine the photos and consider it. Size: 30mm x 22.5mm x 18.5mm Weight: 13g I don't think there are any noticeable scratches, but I would appreciate it if you could accept it as a used item that has been stored at home for a long time.
