A small hand lens made in the USA for children with an ammonite fossil logo printed on one side. This handy little magnifier has two optics which each offer x 5 magnification, however, when overlapped, produce x 10 magnification instead. Suitable for children over the age of 6, the lens will allow them a close up view of the world around them from rocks, minerals and fossils to insects, amphibians, plants and more.
