Brand new, authentic product. ↓ Trivia from the NEST store manager, Japan's number one fin fanatic (tested around 230 fins)... The highly anticipated Mark Richards Future Fins. I've included size comparison images with Captain Fin's Troy Elmore fins in images 4 and 5, so please use them as a size guide. A design that makes you want to buy it just for the look! I also compared the size with the FCS2 Mark Richards 2+1 fins, and they were exactly the same size. I think it's a fin with a size that's not too small and not too big, making it easy to use. *Due to simultaneous sales in the store, if it sells there, this listing will also be closed. Thank you for your understanding. m(_ _)m *As this is a retail product from an authorized dealer, any B-grade items mixed in with the new ones have been checked and removed. There are no B-grade items that are advertised as new. Of course, there are no fakes, so please feel free to purchase with confidence. (^^) If you have any other questions, such as whether we have the fin you want that you can't find on Mercari, or a comparison of the ride feel of this fin with the one you're using, please feel free to ask in the comments section. I will answer as best I can. *Please understand that there may be some color differences between the photos and the actual product. *You can purchase it as is. *The fins listed as "brand new, 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 very sensitive to such details. *We generally do not accept price negotiations. m(_ _)m If you have any other questions, please ask in the comments section.
