FIREFLY DICE - These glow-in-the-dark polyhedral gaming dice contain the color scheme: Clear with a Glow-in-the-Dark Firefly Living Inside, and Bug Green Numbers. This super cool Radiant Dice set has a summertime firefly caught, not in a jar, but in a die!? Give it time in the sun (or any other light) to absorb its powers, and then let it roll in the dark!? You'll still be able to read the numerals from the light emanating from inside this Radiant-Inclusion die.? Kind of inspiring actually. Inclusion Dice are a wide variety of customized dice designs that contain unique items of any possible material or design inside each die!? As every set's design is entirely unique, like our Sui Generis dice, though these ingenious sets are identified by their inclusions! Radiant Dice are premium resin dice that Glow-in-the-Dark (GID)! This set is both an Inclusion Set AND a Radiant Set! Each die has the high and low numbers centered on the color halves for high-speed number recognition. Made of high-impact resin, with the unique casting process we invented 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!
