It isn't often you can find a whole set of vintage Fire King custard cups. They have the scalloped edge and are the #422. They are 5-oz and on the bottom it has T.M. REG. Fire-King Made in the USA with the #422 at the top and 5-oz at the bottom. They are 2-1/4-in Tall, the base is 2-in Wide and the top is 3-3/8-in Wide. Two of the cups also have numbers between Fire-King and Made in USA. One has a number 1 and the other one has a number 27.
They are in great shape with no chips, cracks or damage. One cup has some glue on the inside bottom from where the original sticker was.
Before packing, the weight is a little over 2 pounds.
