A lot of 4 Racing Tires Drink Coasters

This is a vintage set of coasters in the shape of racing tires. There is 4 in the set but it doesn't come with the holder or anything. Not sure if it had one originally or not. They are seem to be made of rubber and the tire cap is metal of some type that's pretty solid.. It's in great condition with no damage except maybe the odd scratches / scuffs. They don't have any identifying marks on them. It comes as is and will be well packaged to protect it on it's travel if bought.
