◎ Shallow cant angle New, unused twin fins compatible with Future Fins. I received a small portion of custom-ordered fins from a surf shop. Although they are unbranded, they are very clean and cool, and the material is fiberglass, giving them a high-quality feel! There may be slight scratches or color unevenness due to the manufacturing process. This is a great deal for those who don't mind. The color may be slightly different from the actual product due to the resolution of the camera. Please understand. These fins are currently the model with the largest area among the keel fins on sale. They have very high hold, and the wide base that adheres to the board enhances the board's drive performance. Basically, the longer the base, the higher the drive performance. These are custom-ordered fins with a shallow cant angle. The cant angle was designed to be reduced during the order. Fins with less cant have drive and acceleration, which reduces the playfulness of the board. The fins are made with a reduced thickness to improve flexibility during production. These are alternative fins that allow you to experience the power of the wave more directly while utilizing a high level of flexibility for drive. Rare size, only a small quantity available. Next shipment is undecided. If you want them, please purchase them as soon as possible. ◎ The handling will be improved by attaching a separately sold center stabilizer. ☆ Please adjust with sanding, etc., if they are difficult to fit into the box. I only used them once, and they still look good. I'm used to single-fin boards, and I bought these and used them once, but I'm selling them.
