I bought this at an imported goods shop in Marunouchi. I fell in love with it at first sight, displayed behind glass. It's an antique demitasse cup, an old piece. The shop staff said this pattern is popular and hard to find a complete set. It's authentic. The original price was about 30,000 yen. It's a set of 4 cups. The bottom of the cups has some yellowing. Please purchase only if you understand that these are used items. The cups and saucers are very beautiful.
