Chemistry comes to geocaching with this trio of spinning trackable Geomedals in three antique finishes. The fronts feature an atom, microscope, and leaf with 3D details, while the backs have a laser engraved plate adhered to the spinning middle section of the tokens. They feature data from the Periodic Table for tungsten and platinum, whose symbols spell WPt. What geocacher isn't familiar with waypoints? A ring at the top of each allows for easy attachment to an object for travel.
