◎Please see my profile◎ ☆These are custom fins from a surf shop. I was able to get a few. If you want them, please purchase them as soon as possible. ◎XL size, brand new, unused twin fins compatible with Future Fins. They are unbranded, but very clean and cool, and the two colors are Good. These twin fins, despite their size, provide acceleration and a natural feeling. When ordering, the AREA is increased based on an all-round template, resulting in high drive performance. By combining them with fiberglass material used by major manufacturers, they provide maximum drive and speed, and the upright outline allows for quick turns that take advantage of the flex. These are friendly fins that can be enjoyed even in small waves. We also recommend the twin stab specification with a separately sold center stabilizer. The appeal of the twin stab is that it has the speed of twin fins, but thanks to the small center stabilizer, you can enjoy a ride that is easier to control than twin fins. 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 advantage of twin fins is that they take off faster than tri-fins and can be enjoyed regardless of weight. There's no doubt that they will help you improve your surfing skills by riding many waves. ◎The actual colors may be slightly different due to the resolution of the camera. Please understand. ◎I am also selling other items. ◎Size when attached to the board Height: Approximately 144mm Base: Approximately 130mm The box height is deep. ◎There are two types of Future Fin box heights: deep with the "f" mark on the box and shallow with the "x" mark. We cannot accept returns, exchanges, or claims due to incorrect fin box height. Please check your own board before purchasing. Thank you for your understanding. If it is difficult to attach or detach the fins, please adjust them by sanding, etc. #futures #FCS #MR #AMTwin #SUP #Alkali Fins #ModernKeelSunburst #Twinfin #TwinStab #Shortboard #Midlength #CenterStabilizer #TwinStabilizer #TwinStab #MarkRichards #CaptainFin #NubsterFin
