Product overview: The new negative ion material used by Weibo negative ion eye mask is a high-tech material that integrates the function of releasing negative ions, far infrared ray, antibacterial, antibacterial, antiviral, deodorization and other functions. It has the characteristics of high negative ion content, washed-resistant, no radiation, no attenuation, etc. It can continue to release far infrared and small particle size negative ions, and weak laser activates biological current. Ensure continuous and uninterrupted negative ion content.
