set of 8 tiny pure white porcelain plates or coasters, Limoges - France china

Beautiful little white Limoges porcelain plates with an ogee border, about 4 3/4" overall diameter. These are possibly butter pat plates or coasters? Though we can think of a million other uses for these, they're so delicate and pretty. The whole set is in excellent condition - I don't believe these have ever been used.
