This is the ESQUELETO TYPE7. - FRP - Ultrasuede/Solid (Black) - Seat heater (without seat heater remote control kit) - Seat rail set for ND Roadster It was used in the driver's seat of an ND Roadster. It was stored for about a year after being used. The storage condition wasn't very good, and there is some dirt. I don't think there is any sagging. There is rust on the seat rails. This set is compliant with vehicle inspections. No claims and no returns. Also, it will take some time to ship. Thank you for your understanding.
