Laptops and Ipads emit harmful frequencies. Orgone energy acts as a filter for these nasty EMF waves. This orgone energy protector mounts to the back of the screen, with bionized tourmalinated quartz, copper spheres and aluminum shavings, cast in shimmering turquoise polyester resin. The dimensions are 4 7/8" X 3 1/4", and it is 3/8" thick. Quartz is one of the most popular healing crystals, working with all of the chakras. Tourmalinated quartz has black tourmaline running through it, a grounding stone known to protect against electromagnetic frequencies.
