Fire orders King Tulip Bowls

Product Name: Fire orders King Tulip Bowls
Set of Fire King Mixing bowls from the 1960's. They are in excellent condition with minor wear in the colors(see photos). There are four bowls and an extra bowl, which I am thinking is the grease bowl w no lid. So all bowls are: 41/2”,51/2”61/2”,71/2”81/2”. The white coloring has.darkened slightly orders through the years, but it doesn't appear that the bowls were used that much. No chips or cracks.
