This monofin was used almost 15 years ago, but I think it's still in usable condition. Currently, if you were to buy a new one, it would cost at least 60,000 yen. For example, if there's anyone who would like to buy a used one for practice, how about it? It's for those with foot sizes around 25-26 cm. I am also listing another monofin. If you purchase both, I will offer a discount on shipping costs. Thank you for looking!!
