This teapot is enameled on the inside and comes with a matching cast-iron base and a stainless steel strainer. The base serves to protect any tabletop. Cast iron is characterized by its ability to store heat and cold for longer - an advantage for enjoying hot tea longer, but also for cooling drinks. The enclosed instructions for use show how to use this unique and beautifully designed product for a long time with the correct application and material-related longevity.
