This item was purchased approximately 50 years ago. It was kept unused as part of a collection. Due to long-term storage, it has a retro feel. The coloring from the beginning is brown or white inside, as shown in photos 7 and 8. I would appreciate it if those who appreciate retro items would consider purchasing. The teacups are approximately 4 x 7.5 cm. The teapot is approximately 5 x 8.5 cm.
