Protect your car’s tires and more, during storage, with a set of 4 Flatstoppers. I purchased them from the Herrington catalog and they retail for $259. I am selling them because I no longer have my Mustang which they were for. I used them 3 times (3 winter seasons of storing my Mustang in the garage). During the driving season the Flatstoppers were kept in the original box inside my house. I am selling the set for $99. Why so inexpensive? So I am not reminded that the car is gone. I have the original box and paperwork for them.
