Hand held arm lengthener:) This lighted magnifier is great for tiny print and for identifying tiny bugs. It has a precision cast 6X super strength bifocal lens. I used mine to zoom in on a spider mite web to make sure I was going after the right critters. It's good for reading the ever shrinking print on bottles, maps and boxes. 1 3/4 inch lens, 7 inches overall. We'll add the batteries for you.
