MIGHTY TINY DICE! Mighty Tiny Dice are the world first and only resin mini dice! At a base of 12mm, and featuring easy-to-read numerals, these mini RPG dice are dice both you and your GM can agree on. And since they're made with our air-bubble-free resin, instead of with air-bubble-rich acrylic plastics that all other mini dice are made with, they're heavier, denser, and much better balanced than mini dice sets of the past! That's a particularly MIGHTY and TINY die! Our "Metamorph" MTDs are made in one of our color-changing Chromomancy style. These little resin mutants magically change color with the heat of your hand as you play. Having one set is like having two sets! 12mm mini rpg and mtg dice. Made of high-impact resin, with the same casting process we invented for our original Halfsies Dice in 2013 that prevents air-bubbles from forming inside, Gate Keeper Games dice bear the honor of being the heaviest, densest, and most well-balanced resin d COLOR CHANGING: These dice change color in your hands! HOT VS COLD: Thermochromatic technology infused in every die! Cool: Teal and Hot: White. MIGHTY TINY: Measuring 12mm that's one mighty and tiny die!
