(^^) ↓Trivia from NEST store manager, Japan's number one fin enthusiast (tested about 170 fins)... The Hayden Shapes thruster fins, which have been out of stock from the manufacturer. I compared them to the previous Hayden fins, and the fin outline, thickness, stiffness, and weight were about the same. And, as before, the inside hole (a recess on the inside of the side fins like Future Fins Blackstix) was also the same depth, which is rare for FCS2. If you have switched from a Future Fins BOX to an FCS2 BOX and liked the Future Fins Blackstix type fins, you should definitely try these fins. If you have any questions, such as whether we have the fins you want that you can't find on Mercari, or a comparison of the ride feel of these fins with the ones you are using, please feel free to ask in the comments section. I will answer as best I can. *Please understand that there may be color differences between the photos and the actual product. *You can purchase it as is. *The fins listed as brand new and unused are definitely new and unused, but there may be some minor scratches or print misalignments due to the manufacturing process, so please refrain from purchasing if you are sensitive to such details. *We are offering the lowest possible price at the official dealer, so we generally cannot negotiate discounts. m(_ _)m If you have any other questions, please ask in the comments section. Thank you for viewing. (^^) Type: Fins Fin System/Fin Box: FCS2 Number of Fins: Tri-fin
