This is a vintage Arita By Santa Clara porcelain creamer and sugar bowl set.
These pieces are in the Coquette pattern, which is white with a thin lavender line around the top, flowers in peach and plum, and pink and blue dots.
The creamer measures about 4 .25" tall and 5.25" wide including the handle and spout. The sugar bowl measures about 2.25" tall, and 5.75" wide including the handles.
These pieces are in good pre-owned condition, but the sugar bowl is missing the lid.
