The Earth is printed on a transparent blue shooter printed with more than 50 rivers and beautiful full color forests, icecaps, deserts and shadow relief mountain ranges in amazing detail. Made with 100% recycled glass. The moon (Earth's nearest neighbor) is printed on an iridescent white peewee and has graphically realistic surface features, with the mares (the face) and major craters in their proper positions. A portion of sales is donated to environmental & educational foundations.
