Chemistry comes to geocaching with this set of trackable Geomedals in an antique gold coloured finish. 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 data from the Periodic Table in four different designs: FInDs, GeO, SWAg, and WPt. Cutouts in the metal add to the appearance and allow for easy attachment to an object for travel. Each coin is also available individually.
