This is a set of four (4) Fire King sapphire blue “Philbe” custard cups. Fire King produced this pattern from 1941 to 1956. These little cups have a curved side. They are 2″ tall and hold 5 ounces.
They are all in good, used condition. They do have air bubbles in them. I found the one with the most and took close up pictures for you to see. This is because when they were made the manufacturing process was much more primitive than it is now. There is nothing wrong with them.
Take a look at the pictures, and if you have questions, please e-mail.
