This is a flute bag for an H foot joint. It is not waterproof, but it is made of nylon, so it repels water to some extent. General waterproof spray should also be fine. The inside is made of soft boa. There are scratches, but I don't think it looks particularly worn out. Please check the photos carefully. The owner has allergies, so dust, dirt, mold, and insect repellent measures are perfect, making it clean despite being used. The strap may be a little short for adults to wear diagonally. The included strap is unused because I had replaced it with the strap from another bag. To keep the price low, I want to save on shipping costs, so I will fold this soft case to fit it in a Takkyubin Compact box when shipping. If you want it shipped without folding, I can accommodate this by changing the price to +400 yen, so please be sure to let me know before purchasing. I cannot accommodate requests after purchase, so please be aware.
