Small Lighted Magnifier with ample power. This small lighted magnifying glass uses two C-cell batteries (not included) to provide plenty of "on" time. The 1-5/8" diameter acrylic main lens is approximately 1.5x power. There is also a smaller 1/2" diameter high power lens (28 diopter or 8x) segment inset for seeing extreme detail when needed. With its loupe-like body, this magnifier is perfect for map reading becuase it can held steadily over (or set on) the document. Gift boxed.
