Of course, it is better to use stainless steel liner. Stainless steel cups, after all, there are no problems such as scratches and fall off as a whole. If it is a copper-plated cup, firstly, there is a problem that it will fall off or be scratched if used improperly. Secondly, copper will also rust, and the rust produced by copper is highly toxic. Most of the heat preservation pots with stainless steel heat preservation liner are made of food grade 304 stainless steel.
