New, Unused - On Sale! These twin keel fins are made with the same materials used by major fin manufacturers. The fin style is similar to the classic K2, with a wide base design. ◎ Honeycomb structure has a high void ratio and is lighter than general resin foam or plastic. High strength and rigidity: The collection of hexagonal cells provides superior compressive strength and durability compared to other materials of the same weight. Due to the unique flexibility of the honeycomb core, it flexes more easily than fiberglass, achieving "medium flex" with excellent control and response. Because of the honeycomb structure, it absorbs impacts from multiple directions, and the impact is dispersed instead of concentrated, improving durability. All-around performance: Lightweight and with moderate flex, these fins are easy to use in a wide range of wave conditions, from beach breaks to reef breaks. Recommended fins! Experience the outstanding flexibility of the honeycomb core. Can be used regardless of board shape. Recommended fins for those who want to try keel fins. ◎ This is a no-brand product. ◎ The color may look slightly different from the actual product due to the resolution of the camera.
