Turquoise Teapot, Koransha - Color: Turquoise - Bottom Logo: Koransha Thank you for viewing. I am selling this item, which I used three times and then stored away. I purchased it at the Tobu Department Store in Ikebukuro. The exterior has no noticeable scratches or stains, but the interior has some minor staining. Please refrain from purchasing if you are concerned about this.
