arena Aquaforce X ARN-0002W Manufacturer's suggested retail price: 40,700 yen. Size: S Purchased in May 2025 at a swimming school. Worn only twice: once for a fitting and once for a competition. Selling because it's too small. Since it was only worn once for a competition, it's functionally like new, but as shown in images 4 and 5, there is some fraying on the shoulder straps. This seems to be common with this series and does not affect use. Please refrain from purchasing if you are looking for a brand new, unused item. Box, tags, and instructions are not included. Please check the photos. Only the swimsuit will be sold. For those looking for a high-speed swimsuit, how about it?
