Vintage Interpur Kids Made In Korea Strawberry Apron Girl Mug,Plate,And Bowl

This set is so adorable!!! It stacks to show the little girls whole body. It is made in Korea and has stamps on the bottoms. I do not see any chips,grazing, or cracks. There may be some slight discoloration here and there but I don’t see anything noticeable and I think it’s just the way it was made. I’m not sure what it’s made out of but I almost think it’s pottery. The plate measures 7” in diameter, the bowl measures 2 1/4” tall and 5 1/4” in diameter, and the cup measures 3.5” tall and 3 1/4” in diameter .
