You won't regret having one; it's a recommended fin. ◎ Material: Fiberglass This fin is made with a honeycomb core. Honeycomb structures have a high void ratio and are 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. ◎ Please understand that the color may differ slightly from the actual product due to the influence of the camera's resolution. ◎ Size (when attached to the board) Height: Approximately 84mm Base: Approximately 90mm Foil: 50/50 The box height is shallow. ◎ There are two types of Future Fin box heights: a deeper one with an "f" mark on the box and a shallower one with an "x" mark.
