Nagaoka Onsen Swimming School. I bought these because I needed a new size, but they were still too small, so I've only worn them about 10 times. There are no fabric snags or damage. The tag with my name on it has been cut off. Please be aware of this. Black school swimsuit, size S, made of polyester for a comfortable fit. - Color: Black - Size: S - Material: 80% polyester, 20% polyurethane Thank you for looking.
