Chemistry comes to geocaching with this trio of trackable Geomedals in three antique finishes. The fronts show an atom with spinning electrons and 3D details. Each back has a ridged pattern around the outside ring and a laser engraved plate in the centre that is adhered to the token. They feature the chemical formula for Germanium Oxide from the Periodic Table of Elements, which spells GeO. Cutouts in the metal add to the appearance and allow for easy attachment to an object for travel.
