We received a small batch of custom order fins from an overseas surf shop. ◎These are new, unused Future Fin compatible twin fins. They are unbranded but are very clean, cool, and have a great 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 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 reducing 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 reduces looseness during turns and off-the-top maneuvers. ◎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 (marked with 'f') and shallow (marked with 'x'). We cannot accept returns, exchanges, or complaints due to incorrect box height. Please check your board before purchasing. Thank you for your understanding. If the fins are difficult to attach or detach, please make adjustments such as sanding. #futures #FCS #MR #AMTwin #Twinfin #wax #boardbag #shortboard #midlength #twinfin #centerstabilizer #fin #futurefintwinstabilizer #twinstabilizer #longboard #leashcord #twinstab #markrichards #honeycombcore #surfwax #power
