After being used for a period of time, it is gradually grayish black due to the pollution of sulfur and sulfide in the atmosphere. The non-toxic steel wooden door is pure in color, like ivory white. The smooth and clean feeling is crystal clear and soft. It has the feeling of penetrating into the inside. It will not be grayish black if it is polluted by sulfur and sulfide in the atmosphere.
