EASY TO USE - the stickers can be applied on phones, laptops, tablets, PC, TV and other small electronic devices. Just place a sticker on your the back of your phone or on the of your electronic device. EFFECTIVENESS - Each sticker can safely shield from EMF/EMR produced by phones, laptop safe, tablets, PC, TV and other small electronic devices. WHAT IT DOES - Regular electronic devices normally emit EMF (electromagnetic frequencies) and EMR (electromagnetic radiation), which can be harmful to humans. Our cell phone protector sticker shield uses a magnetic negative ions technology, which absorbs and neutralizes ions that are present in EMF/EMR. Slim size: The thin and light body is not enough to make the phone heavy, and the new ultra-thin design allows you to put it on the phone or any other electronic device. You can take it with you!
