Selling my gently used Fantasea Fin 4 from Mertailor!  Size is XL, in black/Jet Orca.
It's only been in the water two or three times.  I notice some fraying in the elastic in the heel (See pictures) but otherwise it's in perfect condition.
Selling it because it's big and I don't really use it anymore (no more pool) so it's taking up space.  
These have a 10-12 week lead time to manufacture new. If you'd like an FF4 SOON, here's one!
