Faraday Bag is 8" x 8" military-grade. Put your phone in it to protect it from the invisible, polarizing 4G and 5G millimeter waves of your phone. Many say this is their favorite product. The Faraday Bag will drop your phone's EMF levels to what BioInitiative considers safe. It has a Physics component where frequencies go in and out, as it is only a 7 mil bag, not an iron-clad cage. You can put multiple phones, remote controls, or FOBs in your car. Put it in the Faraday Bag if you need to sleep with your phone on. It will quiet the invisible polarized waves to allow you to sleep better. Due to the increased signal strength of the cell phones, the phone will likely still ring with it inside, and your alarm will still go off and be heard. Doubling up the Faraday Bags will prevent it from ringing, and your location will not show up on the map or be delayed at least 10 minutes. You can even use the Faraday Bag during the day. The fewer man-made signals around you, the better. So put your phone in the Faraday Bag when you are not using it. It is also ideal for carrying your phone in your purse or backpack. For those who are attached to their phones, this is the best gift.
