Gate Keeper Games Supernova Dice are layered dice, from Gate Keeper Games, featuring two pearlescent colors with a band of perfectly transparent high-impact resin in the center! When viewed from the top they appear to be 1 color, when viewed from the bottom they appear to be an entirely different color, but when viewed from the side they appear to be 3 stunning layers enabling you to see right through the center of the die! Nothing beats the creativity of a Supernova Die! Each die has the high and low numbers centered on each of the two colors for high-speed number recognition. Every set comes in the GKG Dice Tower Dice Case! Made of high-impact resin, with the same original layering process invented for 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 dice on the planet!
