Negotiation on price is acceptable ⭕️ This necklace is designed to be discreet, considering the attention it might draw. It's an n-type CMC pendant containing 1600mg of CMC. The size remains the same, with the main body being approximately 8cm, and it can cut off electromagnetic waves within a range of 1600m. Due to the limited production, there is a limited quantity available. Thank you for your understanding. This necklace is a powerful one, filled with high-purity CMC, designed with your health in mind. It's a must-have for those who haven't experienced results with other CMC products! CMC is said to protect you from all kinds of disturbances that emit electromagnetic waves, such as 5G networks and home appliances, and to maintain both physical and mental health. It is effective in relieving discomfort in the neck and arms, fatigue, and a feeling of tightness around the head. I also carry one with me at all times, and since I started using it, I feel refreshed and can spend every day comfortably without hardly feeling any electromagnetic waves in my daily life. Made of stainless steel, it is safe for those with metal allergies. How about using it as a charm to protect yourself from electromagnetic attacks such as thought-reading? The special magnetic coating on the surface of the main body and the high-purity titanium alloy react to electricity, generating high-concentration ion cluster waves. It has the effect of shutting out electromagnetic waves and eavesdropping radio waves within a radius of 10 meters. You'll see when you use it, but I myself was surprised by this effect! ※Individual results may vary. It does not guarantee any effects. ※The CMC pendant is a tool to protect against electromagnetic waves and is not a medical device. If you have any health concerns, please consult a doctor. *This prototype is an improved version of the conventional product. ◯The pendant type for electromagnetic wave protection has the largest CMC filling amount of 1,600mg and is lightweight. ◯CMC filling amount: 1,600mg Size: 14Φ x 60mm Total weight: approx. 16g Effect: Semi-permanent ◯CMC is effective even near high-voltage power lines, substations, solar power plants, homes near mobile phone base stations, hybrid cars, electric vehicles, Shinkansen, and when using mobile phones. It leads to 5G countermeasures, better sleep, improved concentration, improved memory, brain activation, and autonomic nerve balance adjustment. ◯The CMC technology is a special technology that does not affect the equipment used, so it does not appear in the numerical changes of electromagnetic wave measuring instruments. (It converts only the noise of electromagnetic waves, not the shielding method.)
