材质：铜，一面是凸镜，一面是凹镜
凸镜有如龟壳一般，呈镜面凸出的圆弧形，当有带煞的物体冲来时，凸镜可以将这些煞气卸去。
凹镜在风水中有“吸纳”和“聚敛”的作用，能聚拢能量，可以将财运、吉运、贵气吸引到室内。
One side is convex mirror, another side is concave mirror. The convex mirror is like a tortoise shell, the shape of a convex arc. When there is negetive energies, the convex mirror can repel it. The concave mirror is able to "absorb" and "gather" energy. It can attract wealth, good luck, and noble energy into the premises.
