This is a demitasse cup & saucer by Junko Kanenari. It's very small and cute, and I believe it's a valuable item. Image 6 is a comparison with a regular cup. (This is not the product) I have never used it, and it has been displayed in a display case. Because it is a rare and expensive item, if you make an immediate purchase, I will include a chopstick rest by Kanenari (Image 10). This is also cute and has never been used. Please purchase only if you understand the unique distortions, unevenness in firing, and color variations characteristic of the artist's work. Please refrain from purchasing if you are looking for a perfect product or are concerned about minor details, as this is a home-stored item by an amateur. Thank you for your understanding.
