Chemistry, Christmas, and geocaching combine with this spinning trackable geomedal. 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 holmium, whose symbol Ho is used to give the trackable a Christmas flavour. A ring at the top allows for easy attachment to an object for travel or to hang on your Christmas tree and make it trackable! It is also available with other versions in a set.
