After burning 800 degrees, the natural glaze color is burned to 1230 degrees, and finally the color is finished with gold acrylic + protective paint. The part of the acrylic paint is drawn by a pen and it is not easy to complete. Contour lines are free, the colors are elegant, the circular shading and the golden dots complement each other, only one piece! The part of the back pin is made of brass, which is a very good texture of brass, which is disassembled by pulling the rear part of the circle. *This product is made of non-toxic color glaze at high temperature. *Tao itself is not too heavy because of its delicate relationship. * Need to avoid alcohol-based liquid contamination, and strong scraping with hard objects.
