This is a NAISH WINGSURFER MK4 5.5. It has excellent airflow and is a very easy-to-ride model! I haven't used it extensively, so there is a feeling of use, but I think it's still usable. It is sold as is, as shown in the photos. *Please refrain from purchasing if you are sensitive to used items. *Returns and refunds are not accepted. *Please check the photos carefully for the condition. *If you have any questions, please feel free to ask.
