Thank you for viewing! I am offering brand new honeycomb fins, perfect for the popular retro fish and twin fin boards, at a discounted price of 5500 yen (less than half price!). Please take this opportunity to try them out. The size is large, with a base of 14cm and a depth of 15cm, making them ideal for all twin fin boards. Shipping will be via Kuroneko Yamato's cash-on-delivery service. Please note that this product is also for sale next to Sushiro in Kamakura, so we apologize if it sells out.
