This is a RARE vintage Hawaiian souvenir Coaster set. There are 6 in the package and it is sealed in original packaging. ( I am not opening it to photo all the coasters). There are 3 designs two each I was told., However we have a set and it has 4 designs (two duplicated and two individual.) See last picture of ours. Measure of thicknessin photos. They are not found anywhere on the web.
