Hayakawa nickel silver teapot and coffee pot. Size: Height (to the top knob): Approximately 15cm Width: Approximately 20cm (from handle to spout) Diameter of the top opening: Approximately 9cm Nickel silver is an alloy of copper, nickel, and zinc. It discolors over time due to reaction with air, so I polished it with silver polish for this listing. I purchased it quite a while ago, and although it has been restored to a beautiful silver color, I polished it with too much force, so there are small scratches overall when held up to the light, and some areas where the cloudiness doesn't come off completely. Also, the areas in photos 5, 6, and 7 were difficult to polish, so the color didn't come off. (The color might come off if polished more thoroughly) It has only been displayed and is unused, so the interior is clean as shown in photo 3. Please understand the above circumstances as it has been stored at home for a long time before purchasing.
