This is a Sado Shudei (red clay) teacup purchased at an antique market. The sheen that comes with use is nice. It seems like it will become even shinier with more use. Tea stains remain on the inside. Please clean it before use. According to the seller, it's from around 50 years ago based on the design. There don't seem to be any noticeable large chips or scratches. Please check the images carefully. Size: Width: Approximately 7 cm Height: Approximately 9 cm
