Thermal inspection data

After the BIO ION necklace is worn, the temperature of the fingers starts to rise. The chart shows that it rises for 5.2 degree after 20 minutes. The temperature of the toes also rises for 2.7 degree. From the illustration it can be seen that the temperature of the whole arm rises. These results indicate apparently that BIO ION necklaces have effect onsymptoms caused by cold factors and circulation obstruction sufferer.

※  Through various activities, we invite the customers to experience improvisationally and measure the effect. (In case there are too many customers, it may be impossible to let all of them experience.)
