Thank you for viewing. First, items won by March 1st will be shipped by March 3rd. However, the Mercari staff will be unavailable until March 10th, so shipping and responses to questions may be delayed. Thank you for your understanding. This product is the DMC Super Fin ML Blue. It's a top-selling fin loved by swimmers of all levels, from beginners to advanced. The size is suitable for those with feet around 18cm. It's a soft fin, so it's less likely to cause foot pain even when worn directly. It can also be used for skin diving and bodyboarding. The price is around 10,000 yen, but since this is a new sample product, we are offering it at a discounted price of 6,000 yen. Shipping will be via Kuroneko Yamato's cash-on-delivery service. Please note that this product is also sold at SHORES, located next to Sushiro in Tehiro, Kamakura City. If it sells out there, we apologize.
