This is a school swimsuit from Footmark. It's made of 2-way material, so it's stretchy. Brand new, unused, and discontinued. The packaging may be dirty due to long-term storage. The size is L. I do not offer discounts, so I will not respond to price negotiations or inquiries. Thank you. For Mercari shipping, I may change between Yu-Yu and Raku-Raku at my convenience.
