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 data from the Periodic Table for tungsten and platinum, whose symbols spell WPt. What geocacher isn't familiar with waypoints? Cutouts in the metal add to the appearance and allow for easy attachment to an object for travel.
