On Sale! NEW Item! FCS Compatible Brand New, Unused I received a portion of custom-ordered fins from a surf shop. I don't know the model name, but it's a model designed with CAPTAIN FIN twin fins as a benchmark. These twin fins are suitable for surfers seeking speed and freedom of movement, especially the gliding performance in small waves is attractive. Due to the reduced resistance, take-offs are quicker and less likely to be overpowered by the wave, and the speed after starting to ride feels faster than with tri-fins. It broadens the range of board control, improving the precision of turns for beginners as well as intermediate to advanced surfers. Twin + trailer fin setups (sold separately) are also recommended. 2+1 fin setups are for surfers who prioritize stability and control, and they perform well in a wide range of wave conditions. The choice depends on the wave conditions and riding style. The material is fiberglass, using materials also used by major manufacturers. ◎ No accessories included. ◎ There may be slight scratches due to the manufacturing process. This is a great deal for those who don't mind. ◎ The color may be slightly different from the actual product due to the resolution of the camera. Please understand. Size: Twin Fins: Height: Approximately 141 mm Base: Approximately 128 mm If it's difficult to fit into the box, please adjust with sanding, etc.
