Price negotiation OK Set sales OK Designed as a necklace to be discreet. This is an n-type CMC pendant containing 1600mg of CMC. The size remains the same, with the main body approximately 8cm, and it can cut electromagnetic waves within a range of 1600m. Due to the limited production, the quantity is limited. Thank you for your understanding. This necklace is filled with high-purity CMC, designed to promote your health. 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 electromagnetic interference, 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. Made of stainless steel, so those with metal allergies can use it with peace of mind. How about using it as a charm to protect yourself from electromagnetic attacks such as thought eavesdropping? 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. This has the effect of shutting out electromagnetic waves and eavesdropping radio waves within a 10-meter radius. You'll see when you use it, but I myself was surprised by this effect! *Individual results may vary. This does not guarantee any specific results. *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 previous product. ◯CMC filling amount: 1,600mg Size: 14Φ x 60mm Total weight: Approximately 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 (bullet trains), 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.)
