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 data from the Periodic Table for sulfur, tungsten, and silver, whose symbols spell SWAg. What geocacher doesn't like cache swag? A ring at the top allows for easy attachment to an object for travel. It is also available with other versions in a set.
