Chemistry comes to geocaching with this trackable Geomedal in an antique silver coloured finish. The front shows an atom with spinning electrons and 3D details. The back has a ridged pattern around the outside ring and laser engraved foil in the centre that is adhered to the token. It features data from the Periodic Table to spell out OH NO NaNoS. Cutouts in the metal add to the appearance and allow for easy attachment to an object for travel.
