MagniTouch is a 3x power touch activated loupe. It has 3 super bright LED lights and a crystal clear glass lens. Use the on/off switch for “steady” light setting. The twist-action focus allows you to “zoom-in” for greater detail. The MagniTouch is a great magnifier for detailed inspection, to view stamps and coins and for reading fine print or as a desk accessory. Uses 2 CR2016 batteries (included).
