These shungite rectangle plates measure approximately 1" by 0.6". The circle plates are a little over 3/4".The idea is that each plate comes with a sticky tape on the back that allows them to be attached to a cell phone or a computer to protect from harmful radiation. Since shungite does not get saturated with negative charge it acts as electromagnetic protection.
