CMC 3000mg Zero-Field Electromagnetic Wave Protection Coil! ✅ Recommended as a trial purchase to get started with CMC products! Image 2 is a comparison image with the Circle Defender. I personally tested it for about a month before listing it, and it had a tremendous effect in alleviating discomfort caused by electromagnetic waves and 5G, even in crowded areas of the city and in areas with tall buildings. My personal impression is that when I hold this product in my palm, I feel a gentle, comfortable warmth that I don't usually feel, and I think the zero-field effect is also present. ☟ The following is a product description. 【Diameter】Approximately 4cm (variations may occur) This product is mainly intended to be carried around.
