This is a size M. It's a competition swimsuit from arena, but not a woven fabric (high-speed swimsuit). The FINA mark and logo are intact, and it's in very good condition with minimal use. There are no tears. Of course, it can also be used for practice, so it's recommended for time trials and for those who don't like high-cut swimsuits. It's also highly recommended for beginners. It's suitable for a wide range of people, from children and junior high school students to mothers who enjoy swimming as a hobby, especially those who may not have the strength to use expensive swimsuits yet. It's in good condition and I don't want to throw it away, so I'd like to pass it on to someone. I'm open to price negotiations. Please understand that this is a used item stored at home, and those who are sensitive to such things should refrain from purchasing. Same-day shipping available. Price negotiable.
