This is an authentic product purchased several years ago from CMC Research Institute. I placed it in my home as a countermeasure against electromagnetic waves, but a few years ago, I bought another product that does the same thing, and it's a waste to have both, so I'm putting this one up for sale. I will include the general catalog materials enclosed by CMC Research Institute. The excellence of the stabilizer is explained. ※ The world's first carbon micro coil (CMC) is densely compressed and filled, and it can protect against the effects of electromagnetic waves and geopathic stress (geomagnetism). Please install it in the center of your home or office. ー [Effective Range] Approximately 50m radius space (100m diameter) [Specifications] CMC filling amount: 5g [Color] Red [Size] Bottom diameter 4.5 x height 12cm [Total Weight] Approximately 140 grams ⭐️ Expiration date: Semi-permanent The paint on the bottom is peeling, but it's in an unseen area, and there shouldn't be any practical problems, but if you are concerned, please check the photos.
