FireKing Jadite C Cup

These cups are the only ones like them I have ever seen. They are marked Fireking and very heavy. They hold just 5 oz of fluid. They may be hot chocolate cups but I have a standard one of those shown. They are shorter than the D cups and are in excellent condition. Although I have listed them with a C handle it is not the standard C handle look at the picture. Thanks for looking.I have 4 to sell price is per each. although I show two.
