This piece of technology contains the same materials as our Cell Phone Harmonizers. The Pocket Harmonizer was designed using specific materials to harmonize and transmute the EMF signals that come into our space. The composite material is a matrix of specific materials and geometries that are designed not to block the EMF signal but rather change the spin field (information field) to one that is harmonious. It is the thickness of approximately 4 credit cards and can easily be placed in your wallet, purse, backpack or pocket. It is perfect for those that do not always travel with their phones but are still looking for EMF protection. These are perfect for students and children who are surrounded by wifi signals in their schools.
