This is a set of heavy cloth, canvas(I think) Miata seat covers.  They were installed in a car I purchased  but the seats underneath were fine so I took these off.  They have some very mild fading on the headrest area (flash on the camera makes it look much worse that it is).  These will fit any stock Miata seat from 1990 to 1997.  They have two elastic loops at the base to go into the slot between the seat base and back.  And have elastic around the bottom that can be tightened.

This will be shipped USPS flat rate with insurance and tracking.
