Journey to the dry, desert planet of Tatooine with our Star Wars-inspired cup coaster, crafted from 100% Diatomaceous Earth. Its incredible water absorbency instantly removes any excess moisture, similar to how the desert sands soak up the planet's scarce water supply. With its powerful antibacterial properties, our coaster prevents the growth of mildew, just as the harsh environment of Tatooine inhibits life. Perfectly sized to fit most car cup holders, our coaster allows you to bring the spirit of Tatooine along on your travels..
