I was looking for such a material because I do not like fluorine processed products. Because it is an old-fashioned office, the thermal power source is like an electric heating stove, but it can be used without problems and usability is almost satisfactory.
Although I think that it is inevitable to feel a little weight when it is accustomed to the fluorine processed product, it does not matter how it is due to the material and due to the material of safety.
The only thing I would like to improve in the future is that there was no description of Japanese even though the manual was in various languages. I could do it properly to see and use illustrations, but I got a little confusing with how to put the handles.
