Thank you for viewing. 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 trainers. 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, it is available at a bargain 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 is sold out there, we apologize.
