A small quantity has arrived. ◎ These are new, unused twin fins compatible with Future Fins. They are unbranded but are very beautiful and cool, with a good color. The material is fiberglass, giving them a luxurious feel! There are slight scuffs and color variations due to the manufacturing process. This is a great deal for those who don't mind these minor imperfections. Please understand that the color may differ slightly from the actual product due to camera resolution. These fins are designed with the Power Twin as a benchmark, although the size is slightly different. The POWER Twin has a large surface area within FCS's twin fin range. Its calculated design allows for hard turns. - By suppressing the sweep angle and having a wide base and long tip, it enhances drive and speed performance. - By not making the height too large, it maintains maneuverability and suppresses looseness during turns and off-the-top maneuvers. ◎ Attaching a separately sold center stabilizer will improve maneuverability. I have other items for sale. Surf Prime ◎ Size Height: approx. 146mm Base: approx. 131mm Flat Foil The box height is deep. ◎ There are two types of Future Fin box heights: deep boxes with an "f" mark and shallow boxes with an "x" mark. We cannot accept returns, exchanges, or complaints due to incorrect fin box height. Please check your board before purchasing. Thank you for your understanding. If the fins are difficult to attach or detach, please adjust them by sanding. #futures #FCS #MR #AMTwin #Twinfin #wax #boardbag #shortboard #midlength #twinfin #centerstabilizer #fin #futurefintwinstabilizer #twinstabilizer #longboard #leashcord #twinstab #markrichards #honeycombcore #surfwax #power
