304 stainless steel reservoir, spout and lid underside
Where we checked it: amazon.co.uk ›
Saki states the reservoir, spout and underside of the lid are 304 stainless steel, and that every surface touching hot water or steam is metal. It is one of the few temperature-control kettles we found with a metal lid underside.
