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 XXL Blue. These fins from a top manufacturer are loved by swimmers of all levels, from beginners to advanced. The size is suitable for those around 28.5. Because they are soft fins, they are less likely to cause foot pain even when worn directly. They 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 Yamato Transport (cash on delivery). 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.
