Must-sell item! Super popular! Brand new, authentic product. *This is the Future BOX type. ↓ Trivia from Japan's number one fin fanatic (tested about 230 fins) - NEST store manager... The honeycomb version of the super popular and hard-to-get yas thruster fins is now available! Lighter, with increased fin flex, and excellent performance! *The fin box positions differ between twin stabilizers and thrusters (tri-fins). Therefore, even if you attach twin stabilizer fins to a board with a thruster fin box position, it might feel a bit loose and not provide good drive. If your board has a thruster fin box position but you want to ride it like a twin stabilizer, try these fins! They will give you a response very close to a twin stabilizer setup! (^^) I think these are very well-balanced fins! * The yas thruster fins have three cores (image 3), and the GUCCI store manager uses them differently: glass for larger waves, honeycomb for standard wave sizes, and carbon for small waves. Although all three have the same template, the riding feel is completely different, showing the depth of fins. ↓ yas thruster fin explanation video * Copy and paste the URL below into Yahoo! or Google to search. https://youtu.be/24441206aIw?si=s9H5OLqFQuafgsmJ * Due to simultaneous sales in the store, this listing will end if sold there.
