Benefits: The stone in the steaming room is mostly Lingbi stone. First of all, the function of bian stone is mainly due to the crystal structure and element composition of bian stone, which leads to its round material, and its ultrasonic wave is even higher than that of sheep fat jade, so it is mostly used in scraper and comb;
Disadvantages: this kind of ultrasonic wave can only be generated by vibrating the bian stone here, while the bian stone quietly embedded in the tourmaline steaming room has no such effect, but its radiation is lower than that of marble bian stone, which is suitable for health preservation.
