Chemistry comes to geocaching with this spinning trackable Geomedal in an antique gold coloured finish. The front features an atom, microscope, and leaf with 3D details, while the back has a laser engraved plate adhered to the spinning middle section of the token. It features the chemical formula for Germanium Oxide from the Periodic Table of Elements, which spells GeO. A ring at the top allows for easy attachment to an object for travel. It is also available with other versions in a set.
