A small quantity has arrived. ◎ These are new, unused twin fins compatible with Future Fins. They are unbranded but are very beautiful, cool, and have a good color! The material is fiberglass, giving them a luxurious feel! There may be slight scuffs or color variations due to the manufacturing process. This is a great deal for those who don't mind. Please understand that the color may differ slightly from the actual product due to camera resolution. These fins are benchmarked against Power Twin, although the size is slightly different. 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-tops. ◎ Attaching a separately sold center stabilizer will improve steering performance. We have other items for sale. Surf Prime ◎ Size Height: approx. 141mm Base: approx. 132mm Flat Foil The box height is deep. ◎ There are two types of Future Fin box heights: deep with an "f" mark and shallow 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 it is difficult to attach or detach the fins, please adjust them by sanding. #futures #FCS #MR #AMTwin #Twinfin #wax #boardbag #shortboard #midlength #twinfin #centerstabilizer #fin #futurefin_twin_stabilizer #twin_stabilizer #longboard #leashcord #twinstab #markrichards #honeycombcore #surf_wax #power
